How to deal with jealous sister in law

44 replies

L00k4m3x · 30/03/2024 11:19

Me and my partner have been together for 9 years and in that time it has always been very apparent my sister in law is a very jealous person. The day I first met her she said ‘don’t you dare have a baby before me, you’re not allowed’ I laughed at the time assuming she was joking but my partner told me later on during the drive home that she was in fact very, very serious.

We did go on to have a child before her and her reactions shocked me tbh, she was actually quite pleasant. She had her first child 3 years later. It is only since we’ve had our second (and now pregnant with our third) her jealousy seems somewhat out of control. For example before even getting pregnant with our second my partner called her one day to talk about something he had found out about their dad. He said ‘I need to tell you something’ in which she replied ‘You’re pregnant?!!’ And after he said no she responded with a very loud ‘OH THANK GOD!!!’ I heard her on loud speaker and I was so shocked.

She has also made comments about us getting engaged before. Last year my partner briefly spoke about wanting to propose in the near future and his sister told him he wasn’t allowed to until she had gotten married first.. she isn’t engaged yet either, so how long does she expect us to wait?

Anyway fast forward to this year and we are very unexpectedly pregnant with baby number 3 and this time we waited until the 12 week scan to announce it (my anxiety has been very bad during this pregnancy for some reason). At the 12 week scan we were actually 14 weeks. We had a gender scan booked a week later and thought well, we’ll find out the gender and then tell people. We have 2 boys and found out we’re expecting our first girl!!

I was over the moon and told my family immediately. My partner was actually quite nervous to tell his because of how his sister acts. So he told his mom first and she reacted very cold, made it all about his sister and how she’s not going to be happy etc and even said ‘she will be very frustrated’ he has now messaged his sister and gotten no response, no congratulations etc.

I just want to add his sister is in (what appears to be on the outside) a very happy relationship, she has a 3 year old which she conceived on the first try, oh she likes reminding us of that whenever she can as she knows our two boys took a year each time to conceive. So it’s not like she’s stuck in her life, she likes to constantly remind us how amazing her partners job is etc all the time too, so why she is so unhappy for us if her life is so amazing I’ll never know?!

I don’t know what I want from this post really, writing it out has helped. Maybe similar stories of jealous family members? I’m a very anxious and overly worried person who convinces herself she’s in the wrong and I’m sat here a lot of the time trying to figure out what it is I’ve done to upset her so badly?

Just a little update.. I posted the video, neither his mom or sister liked it. Nobody has said anything since either. I think you guys are right, it’s time to little by little cut ties. It’s not worth getting upset about.

Gently, I think cutting ties over not getting social media likes is a bit extreme. Some people find the sharing of such private moments on social media odd and a bit much. Maybe they haven’t been on social media since you posted?

L00k4m3x · 31/03/2024 12:35

@YaWeeFurryBastard Oh it’s not being done because of that and that alone. It’s a build up of everything and after speaking with my partner a lot about it yesterday I think it’s for the best anyway. Not cutting ties forever sort of thing but distancing ourselves a bit whilst we want to enjoy this happy time and not allowing them to take some of the enjoyment away from us!

I think that makes more sense, it sounds sensible to distance yourself if this is upsetting you. Wishing you a happy and healthy pregnancy ☺️.

Not impressed with your mil much either to be honest.. what was her reaction about... disg to he honest.

pinkyredrose · 31/03/2024 12:59

she knows our two boys took a year each time to conceive.

Why the frig would she know that!? 🤔

Just ignore the stupid bitch.

TellySavalashairbrush · 31/03/2024 13:10

I think this type of situation is far more common in families than one might think. I also think over sharing has something to
do with it too. No way I’d be telling sil or mil that I’m struggling to conceive or that I’m waiting on a proposal for example, yet many families do this. I’d also keep family meet ups to every now and then, it reduces the risk of drama. Congratulations op .

TruthorDie · 31/03/2024 13:12

Personally l would do nothing, apart from taking a big step back. That includes your MIL as she’s part of the problem and the dynamic. My MIL (who is far from perfect!) would be over the moon if l announced l was pregnant again. Your SIL is batshit, everyone needs to stop feeding into and enabling her behaviour. I have a family member like this, EVERYTHING is about her and it’s exhausting. I am NC with her as the dynamic is infuriating, plus l have children and don’t want them witnessing this bullshit

Congratulations!

CoconutAirways · 31/03/2024 13:14

Your mistake was to indulge her in the first place . She should have been set straight the first time she tried imposing her shit on to you both.

L00k4m3x · 31/03/2024 13:15

@pinkyredrose @TellySavalashairbrush I think it’s just come up in conversation before. She mentioned before her first she was going to be trying and said ‘I give it two months max and I’ll be pregnant’ in which I went on to say realistically it doesn’t always work that way and said how our boys took almost a year each time to conceive, even with no known fertility issues. She’s always been like that though apparently, super obsessive when it comes to planning things, she definitely likes to be in control I think! Which I think is why she doesn’t like this current scenario as it’s all out of her control. The marriage thing was my partners fault, I think he mentioned when her partner would finally propose in a joking way and said ‘I’ll be asking my name before he asks you at this rate’ in which she responded saying he wasn’t allowed and what not.

Yes definitely go low contact. His dm doesn't sound very nice either.
Congratulations 🎊 enjoy your lovely family.

Maybe have Christmas at home this year and avoid the drama llama?

IncognitoMam · 31/03/2024 13:17

Why not have a very small wedding just a couple of witnesses and dcs? You can propose it?

Sicario · 31/03/2024 13:19

Her behaviour will never change. If anything, people like that get worse as they get older. I have a sister who is exactly the same. The whole family always pussy-footed around her horrible spoilt-brat behaviour.

The only thing you can do is distance yourself from her. Emotionally detach from her behaviours. Decide not to care what she says, does, or thinks of you.

Look up "Yellow Rock Technique" which is a useful way of dealing with toxic people. Do not share any personal information with her.

Remember that her behaviour is nothing to do with you. It is a reflection of what an insecure, empty-headed envious person she is.

Stay away from toxic people. They add nothing to your life.

Imagine if you came into money/won the lotteryGrin

2chocolateoranges · 31/03/2024 13:35

She sounds like my brothers wife!

they had a baby and got engaged ,years later dh proposed, to me, we got married within a few months, and they booked their wedding for 2 months after ours at the exact same venue, we had our first , they announced they were expecting a baby(after saying they were having only one) then we had our second 6months later and she planned her child’s baptism for 2 weeks after our baby was due to try and take the shine off of our new arrival! Lots of other things but that’s the main ones.

we are no contact due to that any many other behaviours they demonstrate.

FloofCloud · 31/03/2024 13:44

She's a narcissist diva and your boyfriend and his mum enable her frankly deplorable behaviour - what a bitch!!!

With people like this, the best thing to do is just let them say what they're going to say and don't contribute other than to ooh and ahh at what they say.

It can only 'come up in conversation' if you choose to share it.

I've not had anything quite this extreme but my son's father's sister forbid me from getting because she was planning her second and didn't want the focus to be taken from her at all.

I got pregnant regardless.

I'm not having my life choices dictated by someone else's insecurities and neither should you.

Raree · 13/08/2024 18:27

Yeah she's a cunt, my sil is too , she tries to engineer bad feelings between me and my husband, I just reject her even more stupid twat

Nikki75 · 07/06/2025 09:02

She is just totally unreasonable in her actions.
You haven't done anything wrong whatsoever.
You partners mum is at fault for saying the things she said to him regarding the sister instead of congratulating you both on your happy news she is stepping on eggshells around her and enabling this jealousy instead of putting her in her place.
Its jealousy and its toxic, take a step back from them concentrate on your family with your husband and children .
That's all that matters dont waste headspace on someone like this x
