Unsure what to make of it

[Azkaba]

I might be in the totally wrong category here but I would like to ask some advice on my family situation. We are all adults.
Issue is my brother who has always been troublesome and who has recently started therapy (court ordered in case this is relevant). He unexpectedly turned up last night, was quite drunk and upset and even cried. He basically alluded that our father had abused him without saying it outright and he was very upset. My brother and I are both NC with our father, as is our mother.
I hate to admit this because I know that I will sound horrible, but my brother has an awful track record of lying and I am usually suspicious of anything he claims :(
I told our mom today and she got upset too of course and she said “I didn’t know“. I first didn’t think about it much but as I drove home I thought that it was strange and unlike her to say this.
As I said he will lie about anything and anyone without any shame, so I am unsure but I have also never seen him so upset and this time I can’t think of a reason why he’d make this up. It definitely would explain some things about him but I really don’t know what to make of it. My mom didn’t react much but they have a bad relationship and I think I might be stuck in the middle for now and I’m not sure what to do and I feel so guilty. Is there anything I can do and ask both of them without causing more upset? I just don’t know what to do

Have you considered abuse maybe the reason your DB lies and he may not be lying about this? If he has been struggling with the after effects the lies may well have started from there.

Yes, as I said it might explain some things. But then our mother’s reaction makes no sense or is strange at best.I can’t see why he’d make this up and I hate that I’m doubting him

You can start by believing your brother. It's better to have believed someone who has lied, than not be believed after being vulnerable and opening yourself up to someone you thought you could trust.

If you’re already NC with your father for your own reasons I would definitely be inclined to believe your brother, maybe this is the root of his problems and behaviour? Support him, try and talk to him again, sober.

I would probably ask him about it again when he's sober sit him down and ask him in a safe non confrontational way as sometimes people say things when they are drunk but if he still says it happened then I would say believe him and support him to tell his therapist who will signpost go the right organisations

Thank you, I will try. I tried talking to him the next day but he was pretending that nothing happened so I left it and tried talking to our mum.
