Ok long story I know - and it sounds completely U from the title!
My brother is an aggressive bully - and as recently as 5yrs ago has physically attacked and threatened me - hasn't happened since I've prevented there being situations where he has the opportunity. I avoid any contact with him because of his behaviour and trust me he has 'changed' many times, been given multiple second chances and blown them.
As a result I feel very uncomfortable and panicky around him - he has also threatened my parents but they insist on sticking by him and have suggested that he will be at their house for Christmas Day. Me and DD were planning on being there but if he is hanging around there it'll be a very uncomfortable experience and I get especially concerned when he is around DD (2yrs) as I'm protective over her - I see it as my role to protect her from people like that.
Would I be being unreasonable to say to my parents that if he is going to be at theirs for Christmas then me and DD will stay at mine and do the present-opening (from me) at mine? It breaks my heart as I'd looked forward to being with them, but I feel like I've worked too bloody hard scrimping and saving for DD's Christmas to let it be such an uncomfortable and unpleasant experience. :-(
It's not my fault that he behaved that way towards me for so many years - why should I still have to suffer for it because they want to play happy families?
