AIBU to struggle with my sister always offloading negativity onto me?

Am looking for advice for how others who’ve gone through this stage of life have dealt with these family dynamics.

i have a sister (older by 10 years) who I have got along with really well with until recently. We are in our early 30s and 40s. It’s not that we’ve fallen out; it’s that for the last 2 years or I’ve found I just can’t stand her personality and spending time with her. We live close by and in the past have really enjoyed going on walks together, lunch etc etc. and I feel really mean about how I react to her at the moment so would like to know if others have experienced the same?

when she calls or we’re together, she offloads all her worries on to me, usually having got herself into a frenzy about things (like our parents, or some other topic that’s taken her attention that week). I stopped her mid sentence a few months ago and asked her to stop doing this, and that whenever she rang she just used me as an emotional dumping ground. She burst into tears and hung up immediately.

but it’s started again. We recently had a weekend together with a long drive, and it was unbearable- she has pre rehearsed things like : “I’ve been trying to make DH do X but he always Y.” “I always feel like when I see X, Y happens and [insert negative comment]”. “X thing has happened and so I always feel Y”.

but ALWAYS the same phrases. All with really negative intensity. Very often assuming the worst outcomes and worst intentions of people.

I don’t claim to be the life and joy of a party, but I feel like I ca never get a word in edge ways and if I try to change the subject to something lighter, she just sighs miserably. If I try to call out that she’s told me this story FIVE times already this month, she’s like I know I know. I mean, if she knows, WHY REGALE ME AGAIN!

sorry, bit of a long one and not super well explained. But perhaps it resonates with people

Because she wants you to be a sister. Someone she can ask advice from ? Someone she can share problems with. Someone who can be a friend with ?

Not just someone who wants light conversation.

That would happen if the first was in place.

It will dawn on her at some point that the relationship she wants with you is never going to be forthcoming.

This is incredibly unfair on the OP.

I think this is really unfair. OP hasn't said she never wants to hear a negative word or a worry from her sister, she's said she doesn't want it to be the one, constant, unrelenting topic of conversation, which seems quite a reasonable position!

What's changed 2 years ago to kick this off? I'm assuming from what you say she hasn't always been like this?

TheRealMagic · 20/04/2026 09:02

This does sound tough. I think all you can do is keep calling her out on it, and distance yourself. I know that's not what you want - you want to have back the relationship you had before - but you've tried directly addressing it with no long-term change, so I'm not sure it's likely really. It may be that she's going through a particularly negative period that she will come back out of the other side of on her own. Do you get the impression she's like this with everyone, or has she mentally nominated you as her emotional support?
