ImMissingMum · 22/02/2026 21:15

So I've name changed for this as I'm quite a regular poster and although I'm not 100% sure, my relative who fell out with my parents and I five years ago could potentially be on Mumsnet, so I don't want to give them proof by being able to check my user posting history.

Also, apologies that this is a long post, I don't want to drip feed.

Basically, my mum died recently, it's been devastating and my dad and I really struggled with her care at the end as she had Alzheimer's.

My sister died when we were in our 20s, and it impacted my parents and I so much at the time and continued to do so after, as I was very close to my sister and she was my only sibling.

A few years after my sister's death I met my now husband and things seemed to get better. My cousin who I'd always thought would be there for me started making nasty comments, passive aggressive stuff about going on weekends away, telling me to be "thankful" I had a boyfriend (at the time) who had a good job, that I had a good job, that I could afford things, that my parents loved me, etc. She was married at a young age and had two lovely children, but didn't have a good relationship with her parents (my mum's sibling).

Things got worse when I got engaged to my now DH, she was asked to be my bridesmaid in place of my deceased sister, her children flower girls. I paid for the dresses etc yet she was very demanding; I also had to pay for her to come to my hen weekend as she said it was too expensive (it was under £200 for the whole weekend), she moaned about the hotel cost for the wedding (despite living less than 15 mins drive from the venue and I wasn't forcing her to stay it was first refusal I offered), she moaned when I brainstormed ideas for a meal the night before that I was deliberately choosing places her children couldn't eat at (I wasn't, my best friend and I were just throwing ideas out, my best friend was the final bridesmaid).

She'd had mental health issues since our engagement and I was worried, she told me two days before the wedding she was feeling suicidal, I was so upset, I tried to see if she'd prefer no front facing role (i.e. be a bridesmaid but didn't need to walk down the aisle if she felt self conscious), she refused. On the day she didn't want the videographer filming her and was very upset about the make up (which everyone told me was beautiful) then told my dad that she had only started to enjoy the day towards the end of the evening.

We had a family lunch the next day for both sides, including friends from overseas and my cousin walked out early without paying, my friend from overseas was horrified and insisted on covering the missing cost as I was just going to pay for the four of them myself. It had been agreed prior to the meal that my DH and I would hire the room for a few hundred pounds and it was then £10 a head for the actual food, and everyone said that was fine to pay that aspect, including my cousin, so I didn't spring that on her.

My mum's Alzheimer's at the wedding was mostly forgetting or repeating stories, forgetting names and needing guided in case she got lost, so I felt a bit on edge on our wedding day, making sure mum was okay as well.

Fast forward a few months and we discovered I was pregnant, I got a lukewarm response and I think because I was missing my sister so much and knew how excited her reaction would have been I blew up via text and asked my cousin, do you even care?!

I got a ranting message back telling me I was selfish and everything was always about me, that her mental health meant she couldn't be happy but wouldn't apologise for that. There was more horrid stuff, saying her friends all agreed and thought I was a self centred person, etc etc. Probably the pregnancy hormones didn't help, but I cried for days after she sent that.

At Christmas a year or so later her family turned up at our house over 3 hours late, my mother in law was very stressed as she didn't know when to have the hot buffet food ready, I then got a message telling me I'd made them feel very unwelcome in our home, even though I'd hugged them all at the door, their oldest daughter had spent the whole time with earbuds in on her phone, her husband refused to talk to us so my DH, my parents and my mil all assumed they'd had a fight prior to arrival! She denied any wrongdoing, but instead said "I regret the behaviour but it was due to being made to feel unwelcome". When I pressed her, she said my mil had "judged" them. Mil was stressed as she was worried about her food being ruined!

I then discovered from my parents that they'd been transferring hundreds of pounds a month to my cousin and her family for years, even before our engagement, because they'd had money issues and because of her recent mental health, they'd kept doing it.

My dad then decided a few months after the Christmas nonsense to stop the money, my mum's Alzheimer's was getting worse and he wanted to save their pension (where the money was coming from) for my mum's care. It was also because he'd discovered via my cousin's DH (he'd let slip accidentally) that she was getting more sick pay benefits than originally revealed. My dad felt tricked.

After he stopped the money, months and months later after very strange, quite cold texts he suddenly got a written letter telling him he had really upset her by not sending a nice enough birthday card (he had, signed by him and my mum with a cheque), had ignored her daughter's birthday (again they had sent a card with a cheque but not a text), that he'd been cruel and it was his fault she was back receiving mental health support.

This letter was a blow to my parents, my mum especially as she was confused and hurt and the Alzheimer's meant she couldn't remember details and just wondered where her niece was.

Despite trying to stay out of the situation, I was blocked, my parents were blocked and that was that. My mum got worse and worse, no longer had her memories, could no longer talk, then swallow. Became incontinent. Social care had to help, it was awful. Then at the end of last year, my mum died. Dad and I were (and are still) shattered by it all.

Mum was rushed to hospital and we missed her death I was numb, we'd been by her side the whole time then when she was moved she died before we got there. Three days of no sleep then when she died I just felt like nothing was real.

I sent a text telling my cousin she'd died and received a really cold response basically thanking me for telling her, no "I'm sorry for your loss", no sympathies etc. I heard nothing from her parents, didn't even get a text, so we assumed they were back in touch. Just to be sure my dad text my aunt (her mother, my mum's sister).

They all turned up at the funeral but didn't come to the line up to see us. Dad and I felt partly relieved, partly upset that even my aunt didn't line up to pay respects. People saw them together and told us on the day. A relative from my cousin's husband's side turned up and revealed that my cousin had posted on Facebook and changed her cover and profile photos to my mum and her; presumably to get sympathy (but she couldn't express that directly to me, mum's daughter). Many people wouldn't have known she'd cut us off five years ago.

Apologies, sorry and thanks for lasting this long. My question is, would I be unreasonable to message her, tell her I know about the performative Facebook pictures (I came off Facebook years ago) and tell her how disappointing I think it is and also how hurt I am at the behaviour and also not even receiving a text from my only aunt about my mum's death? I want to tell her that I feel lost without my mum, it's making me miss my sister too a lot, I've no more female family other than this horrible cousin, I feel so damaged by this but I feel she'd either get a kick out of knowing how hurt I am, my dad too, and my mum when she was alive, she was upset about it. Almost £10k of my parent's money is now in her pocket. They supported her so much, emotionally too, and I just think she is being so horrible and I think she is selfish, I hate how much hurt it's caused me and I feel so angry right now, because I miss mum and my sister. Should I message?

Yes - rant away
No, dignified silence continues

I would say no, dignified silence. I think you really miss your mom and sister and she just reminds you of your connection to them. It’s also natural women want support from each other but I don’t think she’s in a place to be ready for that. To my read not much good can come of it unless the good is that you just want to talk to her in which case that is ok too. Proceed with caution if you do and set your expectations in advance.

PrizedPickledPopcorn · 22/02/2026 21:21

Nope. Dignified silence. Don’t give her the satisfaction of knowing you notice or care.

Nothing you say is going to make her a decent human being. No point trying.

EmpressaurusKitty · 22/02/2026 21:21

I’m so sorry about your mum.

After my mum died I was furious too. I remember wishing someone would say the wrong thing so I could punch them.

I hadn’t realised until then that anger was part of grief. Yes, this cousin sounds bloody annoying. But I think you should wait at least a month & then consider whether you’d actually benefit from telling her what you think of her, or whether it could somehow backfire.

ImMissingMum · 22/02/2026 21:22

Thanks Loveandheights, I think my grief is clouding me right now I just can't stop feeling angry. I'm not naturally an angry person so I feel ill with it.

Zapx · 22/02/2026 21:23

I’m really sorry for your loss. It sounds like you’ve had an extremely stressful few years. Personally, I’d say maintain your silence. It doesn’t sound like it would do any good to tell her how you feel. She could just hurt you further by whatever she does/doesn’t reply back. Focus now on your Dad and your family. I’m really sorry OP, hope you are able to feel well supported through other friends and family.

Thanks, my best friend says to stay silent but my uni friend says to rant at her! It's hard that's why I thought to ask strangers who don't know and could maybe be more impartial.

I was close to my cousin when we were children; she is at least 10 years older than my sister and I too, so we both looked up to her a lot when we saw her when children. I think it's bringing up a lot of memories of missing my sister as well as my mum and it causes my thoughts to drift to my cousin who was also part of the memories. Then I feel hurt and angry all over again.

UnhappyHobbit · 22/02/2026 21:25

I am so sorry for this, your cousin and that side of the family are hideous for what they’ve been doing to your family all
these years. The thing is they will never change or believe they are in the wrong. Something that helped me with dignified silence is to write them a letter, but never send it. Get it all out and then burn it. It’s very therapeutic and then you won’t have the worry of what is coming next from them.

Miranda65 · 22/02/2026 21:25

You don't like your cousin, OP. That's fine, but just ignore her. Dignified silence all the way.

HardworkSendHelp · 22/02/2026 21:26

Ah OP that’s awful. She sounds unhinged. I would not waste my energy on her. I would not even have informed her of your mother’s death. I would cut all ties and look after yourself and your own family. She is not a happy person. Sorry you have been through so much.

LittleCrumblyBiscuit · 22/02/2026 21:27

Leave it. Just be glad she’s out of your life and take care of yourself xx

SENhelp50 · 22/02/2026 21:27

No absolutely don't go to this empty well. I understand the desire so well. I have dealt with appalling people devoid of any empathy who have behaved horrendously to me whilst on my knees.

The only only way is to sever contact entirely. Have no oversight at all on any social media, no more Comms at all. This is so incredibly difficult and the grief is astounding in the face of your loss already. All this will do is cause you more hurt and pain. Distract yourself any way you can and try accept that they don't care about you at all. Your cousin sounds personality disordered tbh. There's no changing, no appealing, no reason with these types ❤️

Miranda65 · 22/02/2026 21:25

I don't like her anymore, that's the problem. We were close (or so I thought) when younger, I think if she'd always been this way then maybe it wouldn't have hurt as much. I don't doubt that her mental health has impacted this aspect of her, but her cruelty towards me and my parents can't always be excused away due to mental health. We were very supportive when she was at her worst but it got thrown back.

OP posts:
FranticFrankie · 22/02/2026 21:30

Agree- dignified silence. She could well hurt you even more if you engage further with her.
You need to grieve with family and people who love and will support you. Don't give her head-space. It sounds like she's taken enough from your family; support and money!
Very sorry for your loss x

Because you had a bond and connection, you romanticise the good times. It's what keeps people trapped in abusive dynamics, keep going back after awful treating and often trauma bond with people who harm them.

MHealth problems aren't the reason for her behaviour. It is who she is.

NeverDropYourMooncup · 22/02/2026 21:34

It won't help you come to terms with your grief, it'll just give you more pain, whatever her reaction - if any.

Bereavement counselling may help you more - perhaps you could look into that when you feel able to?

FOJN · 22/02/2026 21:34

They all sound utterly toxic. It's a mystery that you were so forgiving for so long.

Do not message. The response will only add to your anger. I wonder whether your grief is making you feel angry enough to tell her what you really think of her and you are unconsciously looking for a cold and uncaring response to a message to give you the justification. Resist the temptation. You may feel better momentarily but it will reopen a wound that will take more time to heal.

Having nothing to do with those family members seems the best thing to do for your own peace of mind. They do not need to know anything about your life. It's painful but so is their behaviour whenever you have contact.

MHealth problems aren't the reason for her behaviour. It is who she is.

Thanks. That's probably what I'm grieving for as well tbh, a bond that was, especially now I feel adrift without my sister or my mum. I mean, I love my dad and my DH and I have two boys but I don't have any other female family members (other than this cousin and her mum, my aunt) so losing mum felt quite final.

And yes, I've suspected it's not just mental health, I've wondered for a while if she has a disorder, her thinking is so warped about everything. Even when her anger wasn't directed at me, she'd hyper focus on really small, unimportant things. Never had any self belief. The weirdest thing that I feel right now as well as grief for my mum and anger about this, is actually worry about how unhappy she is. And I don't think she deserves my worry! So then I feel angry at myself too. Gah.

Thanks to everyone so far. I think yes, I'll not poke the bear and just focus on grieving mum and remembering the good times and my own family. X

SummerFeverVenice · 22/02/2026 21:35

I would go with dignified silence too. Your cousin is clearly very mentally unwell so you won’t be able to reason with her or get her to understand the impact of her words and actions on you. You really don’t need the added stress of dealing with her as well as grieving your mum.

And gently, you need to let the past be the past when it comes to how she reacted over the years to your future husband, the wedding and christmasses. At least you can be sure that she isn’t faking being seriously mentally ill for those sickness benefits! Her behaviour is so inexplicable and extreme, that it might help to chalk it up to her illness rather than her as a person.

Endofyear · 22/02/2026 21:35

I wouldn't send her a rant - what would it achieve? She's already shown you that she's selfish and manipulative and she couldn't care less how you feel. If you send her a rant, she'll just use it to play the victim to others. Just cut her out of your life and move on. What's done is done and nothing will change that. I think you have seen her as a replacement for your sister and she isn't and can never be. I'm sorry for the loss of your sister and your mum and hope that you and your dad can console and support each other. Concentrate on the people you love and who love you - don't waste headspace on your cousin and her parents.

Terser · 22/02/2026 21:39

Another one saying: please don't contact her.

You have managed to get distance from her. The last thing you need is her back in your life.

You are thinking of what you would say to her. But what about what she's going to say to you? It's unlikely to be, "yes, you're right and I'm so sorry," She is very likely to have a go at you instead. And however unfair and inaccurate it was, that would still upset you.

plasbks · 22/02/2026 21:40

OP, this is very easy from an outside perspective.

Your cousin is a total cunt.

All you need do - is precisely nothing. Don't respond to any facebook stuff, don't contact her ever again. She's cut off from now.

Grief is horrific and I am exceptionally sorry for the loss of your mum and sister. You will be able to carry on and this is best done with no contact with this toxic, manipulative thief. Silence is much more powerful than a social media rant, which will come across as unhinged.

PrizedPickledPopcorn · 22/02/2026 21:42

You looked up to her because she was older… at a guess you didn’t really know her that well then. She may have enjoyed the dynamic of being ‘looked up to’ and be unable to function in a relationship of equals. I’m really sorry you lost your sister so young, and now your mum as well. It’s hard.

Your cousin can be of no use to you though. She doesn’t have any of 5he qualities you need right now.

PoppySaidYesIKnow · 22/02/2026 21:42

I wouldn’t, as I know you think it might help you feel better, but it’s likely to only make you feel worse. Maintain dignified silence, in fact I’d go a lot further and have nothing to do with her or your aunt again.

Whyherewego · 22/02/2026 21:42

Would it help to write her an angry letter, get it all out of you. But then dont send it. Burn it !
I did that once with someone and it was weirdly helpful to get it out of me and onto paper.
I am so sorry for your loss OP a

I agree with this. She isn't worth it. And god forbid you draw her on you again.

If it makes you feel better write or type out a full letter telling her exactly what you think of her - get it all out. Then burn it or rip it up.
