How to support brother in abusive relationship?

Hi everyone.

This is likely to be long, but I will try to get the context in so appropriate advice can be offered.

I have a younger brother who got into a relationship around a year ago. They are both in their mid 20s. There were some red flags that cropped up pretty quickly which caused arguments between me and him, because I felt the influence of his new girlfriend was impacting him very negatively - think things like him suddenly blaming others for his problems, only going to work very intermittently. This culminated in a big row with him and I didn’t really involve myself after that.

Fast forward to now, my brother has been going through a huge decline in mental health - we re talking panic attacks, daily vomiting, I think some thoughts of suicide. His ability to work has dwindled to virtually nil. My mum has been supporting him as best she can, and he has tried a couple of different antidepressants which don’t appear to have made a great deal of difference. He has also just been assessed for autism for which we are waiting the report.

Hearing this from afar, I started to wonder if it was some sort of potentially autistic burnout he was experiencing, and finally got to talk to him in person yesterday to try and offer some support and strategies to help him.
The conversation didn’t go how I expected, and he started to disclose all kinds of things about his partner such as:

  • when he speaks about feeling overwhelmed or too tired this is dismissed and he is made to feel like he’s being pathetic.
  • despite not working herself, she leaves “jobs” for him to do when he comes back from work and will become argumentative if he doesn’t do these immediately on his return, despite having been at work with an hours commute each way.
  • when he became upset and began crying - told him he was “fake crying” and it wouldn’t work on her.
  • when he is feeling low she will become aggressive and argumentative about why - if he can’t immediately say why then obviously there’s nothing wrong and he’s causing drama
  • she doesn’t drive, and relies on him to take her everywhere, even places that are less than 10 minutes walk
  • she often wants to go out clubbing, but dismisses him when he says he’s tired and is overstimulated by the noise and won’t go home until 3 or 4 in the morning.
  • as his ASC diagnosis is pending, she dismisses all his struggles as not real, or as inconsequential compared to hers. (She is diagnosed with BPD)

These are just some examples that came out after three hours of conversation yesterday, but the ongoing theme appears to be that he is constantly put down, made to feel less than, that his opinion doesn’t matter and that he basically exists as a general dogsbody to make her life easier. He is not entitled to any time to relax or engage in his interests, and even coming to speak to me yesterday culminated in a huge argument between them because she said it has cut into “their time”.

I feel so upset that this is the treatment he is accepting from her. I know he has his faults as well, but I’ve never seen him look so ill as he did yesterday.

I was quite careful with what I said about her yesterday, focusing rather on questions like “why do you think she did that?” “How did you feel when that happened?” “Do you think that that was okay?”
He was of the opinion that often the behaviour was purposeful and designed to upset him, but then in the next breath she makes him happy and he can’t imagine being without her.

I’m very aware she has been trying to isolate him from his family - policing phone calls and reading text messages as well, so it’s really difficult to know where to go from here to help him.

Thank you if you got this far, any and all advice would be really appreciated.

Your brother sounds like he has a very serious mental health condition and is very vulnerable to be taking advantage.

How does this couple fund themselves?

GKG1 · 18/01/2026 08:41

It’s good your brother has spoken to you, and it sounds like you did really well to approach him with open questions etc that help him spell out for himself how toxic things have come to be. There’s a helpline for men experiencing domestic abuse, think he would ring them? Or you could ring them for specific advice?

I think all you can really do is listen, be supportive when he allows it, keep in rich and don’t let him become isolated and wait until he sees her for what she is.

The more you push it before he’s ready, the further he will get from you and the more his partner can twist your dislike of her/break up suggestions as a narrative that you’re against their relationship and you’re the unreasonable one and then you’ll alienate your brother.

I have been the one in a toxic relationship in my early 20s where my whole family knew it was awful but they never tried to get us to break up, never stopped contact, were pleasant and civil to him and, eventually, I saw him for what he was

Thanks for your reply - his mental decline has been significant over the last year, but prior to being with her he could manage things much better - I think because he had time to regulate himself after work. He worked full time.
I don’t know all the ins and outs but she is claiming various benefits, UC, PIP etc which apparently adds up to around £1800ish. She is housed by the council I think.
She then relies on my brother to make up the difference through his work - he works a physical job. I talked to him yesterday about maybe going home to my parents and going part time (as he currently isn’t managing full time anyway) but he can’t because a) he doesn’t want to leave her and b) they need the money.

Thank you, I wanted to be really careful about pushing him back toward her if I expressed too much to what I really thought, but I did ask him towards the end if he had heard all of this from a friend, what advice would he give them?

He got my drift, and said he would advise a serious conversation and I replied that would be a minimum, and if it was my friend I would be suggesting they rethink the relationship as a whole.

This was when he said she makes him happy, blah blah blah. I did point out that minutes ago he had said she is nasty to him and does things to upset him on purpose, but he didn’t seem to see the two things don’t marry up!

thank you for the helpline, I am open to any and all support for him and for us to help him

Thank you for your experience, I think this is what we re trying to be mindful of - to not give her an excuse to alienate him further.

He went home last night and wanted to talk to her about things from a burnout POV as we d talked about it in depth and how he needs to try to reduce the demands on him, and she turned it round that she’s so upset, we all hate her now, what has he been saying etc.
I just kept repeating to him that I have no strong feelings towards her, this is about him and how to support him.

I know he needs to see it for himself, it’s so hard to see such a decline in a person and not want to intervene somehow 😭

Is there any way to help him to not believe all of these things she says to him?

Thankfully no, they don’t have a mortgage or children together at the moment. However I know she wants children, which for me seems like could be the worst thing that could happen. His mental health is such that I think he would have a breakdown, and I don’t think he d ever be able to walk away from her then.
I m sure lots of people with BPD parent successfully, but if she treats him so poorly, how would she treat a child?

I think he just can’t face the reality of being alone and trying to start over, she (partially at least) sees him as a meal ticket because she can’t afford the flat without him.

They broke up briefly before, (her choice) but when he went to get his stuff she was hanging all off him, crying and hysterical about how she made a mistake, and he went straight back. 😢

OP -

The best advice and support you could give to your brother right now is to tell him to end the relationship.

What you describe is narcissistic coercive behaviour from his ‘partner’ and she is being emotionally abusive.

love can be blind but he will thank you after.

This isn’t love… it’s abuse.

I talk from knowing someone close to me who dated someone with BPD and it really didnt go down well - your brother will get dragged into her tendencies. He needs to make the decision to leave now for his own mental health or it will get worse. Trust me.

See, this is what I m desperate to do, but I m worried then I ll be the bad guy, unsupportive and all the rest and then he wont talk to me anymore, or he lean further towards her.

I kind of tested the waters a bit yesterday and even told him that shes showing him who she is with how she treats him - why aren’t you believing her???

I asked him to come home and he just said “I can’t.

He’s very close with our mum but I don’t think he will have it from anyone.
Much as it pains me and I want it to be different I think it is going to be a case of watching and waiting, and keeping the door open so he knows he can always talk. Try to take some of her power that way. 😭

I even thought about sending him this thread but I don’t think even that would be enough.

Is he getting any individual therapy? Most people, even without their own mental health struggles, don't last long in a relationship with a person with BPD. If he has his own struggles, a relationship with someone like this will just push him over the edge. You need to stay on side with him but if he is accessing professional help, he might come to this conclusion himself. For now, perhaps just make sure, as far as you can, that he doesn't become further enmeshed in this relationship - with kids, mortgage etc.

Unfortunately not. He has had access over the years privately but it never seems to last.
Ill have a look and see what’s available in our area again.
The whole family is desperate for him to not enmesh himself further, but she is desperate for a child which has (thankfully) not happened so far. She is also saying that’s his fault as well and now he’s also worrying about that.
He agreed last night that this would be a really bad time for them to have a child, but then has made comments today about “if something good happens to us” which I can only assume is alluding to that…

your brother is hardly working.
she isn’t working at all

So basically we the tax payer are entirely funding this couple?

YourPoliteLeader · 18/01/2026 14:10

His ability to work has dwindled to virtually nil

so he’s now receiving benefits are living off all her benefits?
