To be weirded out by my future SIL?

Hey everyone, name change as my other info put together with this would be quite outing.
So,
I’m going to give as much information as possible so apologies as this is a long one.

I’m a little bit concerned about my future SILs obsession with my fiancé (for ease I’ll just call him DH).
My DH is the eldest sibling and SIL the youngest, they didn’t have the most loving parents growing up and my DH had a lot placed on him as the oldest and was often beaten/belted/punished in place of his younger siblings, which he took without protest to protect them. His mother ended up leaving his dad and moving in with another unsavoury man and essentially emptied the whole house and left the kids behind. It had a huge emotional toll on all of the children.

My DH being the eldest remembers it very clearly being around 12/13 at the time, his brother was maybe 8 and his sister around 4.
DH is a really wonderful man, but the abuse and abandonment took its toll and he had a very wild time between his teenage years and mid-20s, drinking, taking drugs and getting into trouble with the police.
Despite this he always looked out for his younger siblings and was there for them, albeit not very sober or in a position to do much for them.

He moved out, or more like was kicked out, somewhere around age 16 and lived with friends and their families, passing girlfriends and on campus when he went into HE, so managed to find somewhere to lay his head but it was turbulent and he’s not really had a true home since before his mum left. In the same vein he’s lived with his siblings since around this age either and during this time contact was sparodic but he always tried his best to be there. His sister became pregnant as a teen and her dad kicked her out, DH lived very far away but stayed in touch via text but didn’t meet his niece until she was around 3/4.

After a big blow out with his dad in his mid-20s which led to a short arrest/stay in a county jail he decided he couldn’t continue like he was and instead completely became a bit of a recluse. His dad and him ‘made up’ and he moved in with him and they just co-existed with DH being an emotional punching bag.

Anyway, that’s just a bit of background.

Fast-forward a few years and he and I met in a supermarket whilst I was on holiday in his country, we hit it off right away and he asked for my number. We went on a date whilst I was there but I was going back home shortly after we met but honestly we both knew it was special so we agreed to keep in touch.
We were LD for a year or two and between us we decided him moving here would be the better option. His sister had come to visit him and his dad for the first time in a few years with her youngest child so he thought it was a good idea to tell the family our plans. Well, he told his dad and he was all for it and said it’d be good for him, but when he told his siblings his sister was NOT happy in the slightest.
She left the room and starting drinking then contacted me and advised me this was a terrible idea, he wasn’t over an ex gf, he would ruin my life as he was bad news, he wouldn’t ever love me right and I deserved better etc etc whilst crying in the car. She told me they were all taking bets on how long it’d take him to mess up his ‘new life’ and she bet within the first 24hrs of landing here.

I was a bit bewildered, I’d never spoken to her before this as she lived with their mum about 6 hours away from him with her children, and apart from her texting every now and again or visiting their dads house he didn’t have much contact with her anymore. He said the limited contact was as she liked to dredge up the past whenever they got together and she would just try to rehash all the pain of the past which he remembers much more vividly. He also mentioned that she just liked to talk about herself and her trauma for days and days and stop him sleeping so she can ‘trauma dump’.

I explained to DH what had happened and it turned into a big argument between them with her calling me all sorts of names and him ignoring her for the rest of her visit. He apologised and told me if I had any reservations then he understood, but he loved me and we could extend the time frame if I needed longer to decide. I reminded him I too had a very dysfunctional family so I understood difficult dynamics and we should go ahead as we’d planned.

4 months later he came to the U.K as a test stay to see if he’d be able to settle here, everything went really well and he loved being here with me and we decided to make the move more official.
In his 6 months here he had fallen out with his father who he realised was still very abusive, but needed to return to his home country to apply for a spousal visa and didn’t have a place to stay, so he asked his mum and sister if they would put him up whilst he applied.
They were happy to have him and said yes, so he went back and with the expedition we had his acceptance answer within a week which was brilliant and we felt so lucky.
He FaceTimed me to give me the good news and we started saying how excited we were when his sister started throwing a wobbly in the background complaining how I was stealing her big brother and I was taking time away from her at that moment and she needed this time with him alone.

I brushed it off and explained I’d talk to him when he went to bed and he said he loved me and he couldn’t wait to be home - that further set her off and she said that he WAS home. I gave him a funny look which he shared and repeated what he said and hung up.
He called me later that night and his sister was there, despite earlier I was very nice and tried to ask her lots of questions about her and ‘bond’ with her which she took to, but whenever he and I would talk about life here she would get upset and try and drape herself on him and talk about how much she loves and misses him and doesn’t want him to leave. That she is his keeper and he’s always going to be her favourite person, even above her children, and whilst he was visibly uncomfortable he just put up with it. I smiled, though weirded out a smidge, and said it was lovely they were close and I wish I’d had that sort of relationship with my family.
She then spent until 5am in his bedroom before he asked her to leave so he could sleep as he was confirming his flight back the next morning for 2 days time so he could be back for Christmas with me. Cue more dramatics and a full-on breakdown (despite her knowing this was always the plan regardless of Visa application status as a visa isn’t needed to simply visit from his country to the UK) and she went outside to smoke to ‘calm herself’. He followed her out and told me he’d call me back. That took about 4 hours.

When he called back she was passed out in his bed so he was on the couch about to sleep but wanted to talk to me first and apologise for how she acted. He explained that he didn’t know what her issue was, but that he’d told her off and he’d be home soon so this would be less of an issue. I said it was ok and I loved him and he needed to sleep.
After that every time he was on his phone updating me or simply wanting to talk she would show her distaste and come up with something he needed to do right there and then, even his mum seemed a little embarrassed. When he got past airport security I selfishly did a sigh of relief that dealing with that was finally over, I was apparently wrong.

Over the next two years she would switch between sweetness and light with us to out and out spiteful. Going between calling up DH and refusing to talk if I was around which lead to him hanging up which then had her sending me a bizarre barrage of text messages on every platform I had telling me I had stolen her best friend/favourite person/the best man she knows, to then changing her tune and trying to flatter me and say how much I’ve changed him for the better and how grateful she was that we found one another?!

In the end I told DH I needed to block her for my sanity as she was being truly bonkers, he agreed it was for the best and when she brought it up at the next phone call she went ballistic when he confirmed why. He then told her he didn’t want to deal with her behaviour and he wouldn’t be talking to her again until she got some help, he blocked her and we got on with life.

We got engaged and then I fell pregnant quickly, we were over the moon! He was so excited to be a dad that he told his family right away and unblocked his sister to share the good news too despite my reservations.

She texted and congratulated us and told us she was going to renew her passport and visit for when the baby arrived. I was nice and said that’d be lovely and we’d let her know when the time was right, DH said she could but maybe in time not right away as we’d be finding our feet as new parents. She looked upset but held her tongue and said that was fine.
After this I unblocked her too hoping that the good news would bring us closer and things could be calmer. Instead it became all about how much she’d missed her brother and how brilliant he was and how lucky I am to have a man like him and when she was here all the things she wanted to do with him like go out drinking and find herself a British man so she could stay forever.
I agreed he was wonderful but he would have a newborn so I doubted going out getting hammered was going to happen and that he had changed a lot since they were younger and her tales of him weren’t quite who he was now, she took offence to this and told me to her he would always be hers first and her best friend. I just ignored her message and changed the subject.

DH has been busy at work the last few months and we’ve been saving harder for or baby’s arrival so he’s not really spoken to anybody back home, and a few days ago I woke up to about 8 very long, very angry messages from his sister.
I didn’t even read them, I just passed the phone to DH who then rolled his eyes and told me to ignore them.
When she saw I’d read them and not replied she became angry and carried on sending them, to the point I had to respond as she was spiralling, talking about going and sleeping in his bed in his old bedroom and crying whilst typing her messages. I ansked her to take it up with her brother not me and she again asked why he wouldn’t talk to her and insinuated that I was stopping him or that he was dead and I was hiding his death from her and others.
I was absolutely outraged, I told DH what she’d said and he texted her too annoyed to speak nicely and asked her to stop and he’d call in a few days time, but she just went on and on and then sent him some very long very weirdly OTT message about how she was a mini version of him and she was proud to be and it was her and him forever.
She then said she needed to cut him out of her life and told him not to call her, he just sent a simple ok and left it at that. I’ve now re-blocked her on all platforms as I really don’t need this stress with me being due to give birth in a few month, but I don’t even know what to think of all of this.

As a child from an abusive household I can absolutely appreciate that their childhood had a very profound impact on their lives, especially hers being to young and the only girl who was then thrown out as a teenager. However her behaviour is totally out there and I don’t understand it at all.

DH pulls her up on the truly awful stuff but brushes over the more mid-level aggression she likes to dish out to people around her as he knows she had it rough, I guess it’s him protecting her as he’s always done, but honestly I’m a little creeped out by her behaviour. I’m not sure what her obsession is with him, I guess he is probably the only positive male presence she’s had in her life? Still though, it all seems very OTT when she’s saying it’s crushing her to have him not talk to her all the time and be so far away when they really didn’t speak much or ever see each other when they lived in the same country but now he’s doing well in life and is happy she’s gone a bit mad.

I guess my AIBU is should I be this weirded out by her behaviour and what the actual F should I/we do about it?! It’s gotten to the point I would really rather her not be in our life at all, but I’d never ask that of DH. He’s said he doesn’t want to talk to her as she’s lost the plot, but I find myself defending her and trying to act as if she isn’t batshit crazy because if she ever becomes more stable then to her I’ll always be the one who stopped them talking despite it being of his own free will.

Again, apologies for the long first post, I’m just lay here with pregnancy insomnia with a lot on my mind and wondering if I’m over or under reacting.

Keep her blocked from now on.
Try to enjoy your pregnancy and baby.

Studyunder · 03/09/2025 06:53

Block forever. She will never change. Absolutely NEVER let her visit you. She doesn’t ever get anywhere near your child.

notmymonkeyss · 03/09/2025 06:55

Your dh would be better to cut contact. Your sil has become abusive because of her dysfunctional childhood. She takes that out on your dh because he’s the person she can safely do it with. She’s also testing his boundaries to see if he will leave her too. She’s needs therapy and to get out of her mums.

Thanks for the reply and yes it’s sadly real.

In an ideal world I’d absolutely say this is the way to go, especially with his parents who I agree are both as bad as each other, but I don’t want to almost demand that of him after he’d moved to be with me and start a life here. I think the longer he’s away from there the more he sees it anyway.

I know deep down she’s not safe to be around and is unhinged and I don’t really think she would visit either as she doesn’t like air travel but then I also think to see DH maybe she would? I feel quite sorry for her in a way, but then it’s also not my fault and I really have been nothing other than nice, so I also feel absolutely furious about how she’s acting towards me (and so is DH which is why he needed to cool off before he called her).

Also I didn’t mention his brother as it seemed long enough and based to the PA replies from some on here I was right. 😂 His brother hasn’t ever been in a good place and tries not to have too much to do with them.

You sound like a lovely person who deserves to be very happy with your new family. I wish the pair of you loads of luck and happiness with your fresh starts x

Step back. DH deals with SIL. You don’t want her to visit but she can come. And stay nearby . The end. All the past, all the stress, leave DH to it -you don’t want to hear anything more.

Blimey, I hadn’t realised that would have been so long!
I’m guessing the sister is hurting that the person she’s always looked up to, has found someone (you) and cleared off to another country? She does sound as if she needs a lot of therapy because she’s clearly been screwed up by her childhood.

This!! It is quite likely his sister has a highly enmeshed trauma bond to your dh. He was her parent and protector growing up, whilst everyone else was very abusive and at some point all abandoned her and It sounds like she sees your dh as being another one to just get on with their life and leave her behind. Regardless of your DH claiming he protected the others from the abuse, they were still there, they witnessed things and were also abused themselves (you dont actually know what abuse she experienced herself). It sounds like shes still clinging to any parts of her family she can still get. Ultimately, She does need help to work through all of this and whilst it's not your or your DH's problem to fix, by any means distance yourselves all you like but viewing/calling her weird, crazy and whatever else isn't really going to help anyone. After all, she isn't the devil here.

I know, I guess it was a partial vent too as I don’t have anybody else to really talk to about it without seeming to be badmouthing her and she’s been through a lot.

I can understand the issues stemming from childhood, I have my own scars in that respect, but to suddenly go full nuclear when they’d not spoken much or seen each other for years between him becoming a self described hermit and us meeting I was just a bit taken aback I guess.

He’d told her about me during a short conversation they’d had before he moved and she just changed the subject.

Blimey that was long. Your DH has the choice whether to continue the family dysfunction into another generation. I’d remind him of that. Maybe it will focus his mind.

I wouldn't stop my dh seeing her.

But she wouldn't be in my house and wouldn't have any access to my child in her current state.

I'd be concerned she might harm the child.

She needs therapy and maybe meds

deadpan · 03/09/2025 07:47

Simply put, she's a narcissist. Id go so far as to say she has NPD. In a way it isn't a surprise with the awful upbringing they've had, I mean who abandons their 12 year old to look after toddlers?! The parents sound as though they have mental health issues to do all that to their kids, so she could have inherited it from one of them. It also sounds as though she's been placated becsuse of guilt, which again isn't surprising after they treated their kids so catastrophically badly.
The one thing that stands out more than any other is that she loves your partner more than her own kids. This highlights the abandonment she had as a child, she sees her brother as a comfort blanket and hasn't known how to connect to her own kids.
She needs psychological help, counselling maybe or a psychiatrist. She's a pain in the arse - I know, I have a narcissist sister - but she's gone through a lot and it needs addressing.

Hi, yes we’ve spoken about the boundaries thing before and I’ve mentioned he needs to be firmer if he wants her to step back but he feels bad as she has a dysfunctional life back home so needs more compassion.

I back off as I understand he still feels like he needs to be protective as it’s his little sister, but it’s just inviting in such odd behaviour and he’s really starting to see how strange it is now too.
He said she’s always been very involved with ex-girlfriends and been hot and cold, and then and has kept tabs on them after break ups (bit strange) and mentions them at times and when he says he doesn’t care or is happy for them she gets huffy.

Thank you, I’m hoping she gets some help and we can at the least have a long-distance relationship, the baby won’t have much family at this rate which I know none is better than crazy but still.

Hi thanks for that it’s actually very interesting as I have wondered about the possibility of a personality disorder as I’m pretty sure their dad has NPD and I know my mum was diagnosed herself. Whilst I don’t know what she endured when DH was kicked out of the house but I can’t imagine it was good.

I’m sorry you’ve had experience of this sort of behaviour, it’s really draining.

She said she’s seeing a therapist in a recent text message but I’m not sure how true that is and even if she does have NPD/BPD that she may be able to play the role of someone who doesn’t for a while as those with it are known to do so may not get the help she needs.

Crunchienuts · 03/09/2025 07:59

I mean, I couldn’t read it all but what I did read, why on earth would you want to be involved with any of these people?

Plethorapeach · 03/09/2025 07:59

I know this is about your SIL but being honest I think you might need to strap in because your DHs past behaviour gives you a great clue about what he is likely to do if/when your marriage comes under stress.

He has done absolutely nothing to deal with his past and staying touch with his family who have harmed him so much is a sign that he has not remotely healed. Clearly it was a deeply troubled past.

My own DHs was troubled in a different way but he had put in rock solid boundaries with his sister who has a PD. You have a DH problem.
