I have two brothers, both younger, DB1 is two years younger and DB2 is 14 years younger.
I've always had a rocky relationship with DB1. We lost our father at a young age, and we shared the same sense of humour, so there were things that brought us together and made us feel very close. However, he can be very stubborn and pig headed. I'm pretty sure I can be all sorts of things too.
When my youngest brother was a baby, DB1 had an argument with DM and ended up shoving her over. She hit her head and fell unconscious. I was holding DB2 and I was petrified. DB1 left the house because he needed to calm down. I was never quite comfortable with his temper after that, but after a few years things settled and we became friends again.
I have a great relationship with DB2, he's hilarious, and charismatic, and very self assured. DM sometimes feels left out when DB2 and I are 'bantering' which I don't want her to feel. Sometimes she gets upset about it and feels we're deliberately excluding her, or even talking about her, which makes me sad because I never would.
About five years ago, DB1 and I both had to move back in with DM for a short while (both for different but financial reasons and DM was happy for us to). During this time, DB1 and I would play games and have drinks together and set the world to rights. However, one evening I was tidying up, and I was moving some bags from one room to another. DB1 didn't want the bags moved (they were DMs bags, not his). He stood in front of me and refused to let me move them. I had recently come out of an abusive relationship, so I felt very defensive, and I said to him I'm going to move the bags whether he liked it or not. I made to step forward and he shoved me backwards.
I was distraught. DM was nowhere nearby when this happened but DB2 saw the whole thing. I became very emotional and wanted to leave the house, but DB2 was worried for my safety and told me to stay home. DB1 refused to talk to me since then, to this day he still doesn't. I moved out shortly after because I didn't feel safe around him. I then met Mr. Numbs and we have DC, that DM loves to pieces. But she's sad that DB1 isn't going to meet them.
I've told her that I'm not comfortable for her to invite him over (without him knowing I'm here) to meet DC. I said to her that he would have to apologise first. She's obviously upset about that and has been trying to change my mind. I understand this.
What I don't understand is that she is still unwilling to accept that DB1 did anything wrong. At first she was just repeating that she didn't see it so she doesn't have an opinion. Then when DB2 told her the same story, she said that DB1 must have been upset at how DB2 and I were treating her and he was just defending her and was angry with me. She accepts that he shouldn't have pushed me, but thinks I should let it go and call him to arrange for him to meet DC.
I love DM to the moon and back but this makes me so uncomfortable. AIBU to think she should be more understanding? Or should I do what she wants me to do and let go.
