I'll never forgive them for how they acted although they think they did nothing wrong.
I am currently going through this with my only sibling and this is how I feel.
Had bullying etc from them all my life, started to go v LC when our last parent died, then they suffered an enormous tragedy. I supported them at that time, despite how they’d treated me for many years, and in touch afterwards.
Only to find them on MN a while ago, getting support for tragedy (fair enough), denying my kids existence and slagging my husband off (not fair enough). I was stunned they would stoop so low, esp about DH, he is a lovely man and helped so much when our mum was terminally ill, not to mention when she died. (Am not minimising what they said about DC but they are now adults and couldn’t care less what was said).
I have just had, this week, texts asking why I haven’t been in touch, they don’t understand what they done wrong. So I told them. Cue denial, the posts weren’t them “prove it” (there was absolutely no doubt that the posts were them), no apology but lots of stuff about what my family did wrong after tragedy. All about them.....how the tragedy means they have an awful life and can say what they want about us. Other people suffer tragedies without being twats to their closest family!
Final guilt tripping text about it being my decision to stay in touch etc. It makes me sad that they think so little of us, but I know it is them not me, they have always been very selfish and self centred.
I am not saying this is you Op, as you say you have grovelled and apologised, but if your brother doesn’t want contact, just leave it.
