Ok - back story - I have a brother who is a few years younger than me, we have never gotten on well, he is (at the risk of sounding one-sided) an aggressive bully. I know 'sibling rivalry' (which my parents had put it down too) is quite normal, but this continued into our twenties, I can honestly say I have never been physically aggressive towards him, but he had on several occasions (when I was home from uni) threatened me and hit me (I once had to barricade mysely into my room), usually if he hadn't had his own way, or mum and dad had refused him money/beers/fags/the use of their car.
My parents often encourage me to 'bridge build', and I have buried the hatchet on numerous occasions only for him to repeat the behaviour. He has also been abusive towards my parents. Lots of bullying behaviour etc.
After an occasion last year I decided enough is enough, I do not want him in my life as I'm not stupid enough to believe that he has 'changed' for the millionth time. We now don't have contact unless we happen to be at my parents at the same time (which I avoid - although my parents sometimes don't tell me that he's there).
Brother has now had a child with his on-off teenage girlfriend. Said child is to be Christened soon, my parents are presuming I'll be attending with DD, I said that we weren't planning on being there, I don't feel that it's appropriate and would be very uncomfortable being there. My parents keep saying that it's a shame, all the family will be there, it's important for DD to see her 'Uncle X' etc. I stress to them that she see's plenty of her family, and I don't call him her 'Uncle', she doesn't know him - I don't want her around someone who thinks it's appropriate to treat people how he does (he has, on a few occasions, not controlled his temper with her around, swearing, slamming doors, threatening and verbal abuse etc).
AIBU to stay away from this event, even though my parents will be annoyed with me for not playing happy families?
