AIBU to feel drained by my sister-in-law constantly making things about her?

Hi Everyone
This is something I have been thinking about for a while now. I’d really appreciate some outside perspective on this, as I’m starting to feel quite drained and unsure if I’m overthinking things.
I have a long-term friend who is now also my sister-in-law (she ended up marrying my brother). We weren’t especially close in school, but lived together when we were younger and stayed in touch over the years.

Looking back, I feel there has always been a bit of a competitive dynamic. For example, when we were younger and going out, I often had the sense that if I got attention from men, she would imply (subtly) that I was “lucky” and that they were really more interested in her. At the time I brushed this off.

When I got engaged and was getting married, she had just come back from travelling and her behaviour felt a bit off. On my hen and wedding, she was making comments like I’d been very drunk when I met my husband, and generally joining in with my sisters in a way that felt a bit undermining. The night of my wedding, she got together with my brother, which I didn’t think much of at the time, but the following day the focus shifted onto them. A few months later she even joked that they had “stolen my thunder,” which really stuck with me.

Over the years since, I feel there’s been a repeated pattern where if I share something about my life, she brings it back to herself. For example, if I mention my kids, she redirects to hers. When my father passed away and we were holding the wake at home, she told me (but no one else) about a health issue her own mother was having, and I ended up comforting her instead of the other way around.

More recently, I shared in a WhatsApp group that I’m applying for my boss’s job (a CEO role), which is a big deal for me and something I’m nervous about. Her response was to mention her own work situation and how many people she manages, before wishing me luck. When I said I was nervous, she again redirected to her own worries about her children. I came away from the exchange feeling deflated rather than supported.
There are other small examples over the years, but it’s the overall pattern that’s getting to me. I often feel like interactions with her are draining, and I don’t feel particularly supported or celebrated.

Because she’s my sister-in-law, it’s not a straightforward friendship I can step back from completely. But I do find myself wondering if, had she not married into the family, we might have drifted apart naturally.

I suppose my question is: am I overthinking this, or is it reasonable to feel this way and to start putting some distance in place (e.g. sharing less, lowering expectations, etc.) rather than confronting it directly?
Thanks for reading if you got this far.

Distance, distance, distance. Be friendly when you meet her on a surface level but be super busy and keep that to a minimum. I would develop some fake / minor threads of your life to talk to her about, so as to avoid sharing anything important or meaningful for her to appropriate.

I agree with @BadSkiingMum and your Sil sounds like a frenemy.

BadSkiingMum · 04/04/2026 22:47

That does seem a bit pointed.

I would just take everything down a notch. Share a bit less, reply slower, be warm but a bit less open.

Maybe mentally shift her from friend so sil. See her only with db and stop divulging private stuff to her..
I married my best mate's db.. Sadly when we divorced she took his side even though she knew he was a twat.. I missed her more than him when we split..

You're definitely not being unreasonable! I had/have a friend like this- we fell out and are now kind of speaking again- but I also have another friend whose face literally lights up whenever something nice happens for me- she is wonderful and life-affirming.
Your instincts never let you down,believe me.
The issue is how to minimise interaction when she's married to your brother. Distance yourself, but be prepared for questions- at which point you gently explain everything you've said here- it may do her good.
She must be basically insecure, but that's not your issue to deal with.

I have a SIL like this. Last time I saw her I managed to get away with barely speaking to her. I am hoping to not see her again this year. I can cope with 5 minutes once a year

You could put a stop to it by asking her if there was any chance that she’d be able to not make it about her, but this would probably cause more problems than it would solve.

In your shoes, I just wouldn’t respond beyond a brief acknowledgement. If you post on a group chat and she responds, just give her a thumbs up and don’t even bother reading what she’s written. If it’s in person, then avoid her completely unless it’s superficial. She’s not going to be someone who’ll give you any form of support. If she makes silly comments like stealing your thunder on your wedding day, then just chuckle, roll your eyes and say ‘yeah, alright then’.

I have a very close friend like this. All I can say is im very sorry for you as you can't undo her from being in your life due to her now being family.

I do think its a bit weird she got with your brother almost claiming something of yours in a sense.

If I hadn't experienced it myself I may not have got what you'd been saying but I think with competitiveness you just know in your gut when a friend is doing it. And it kills the relationship because in a way you may either compete back when its not in your nature, then you feel gross. Or you start overthinking every action feeling a bit crazy.

Putting distance is not unreasonable at all. I just can't with people who make every conversation come back to them its so frustrating and hard to like that person or listen to them once you've noticed it
