It's a long story but basically my dad is a nasty piece of work. he has always been mentally controlling over me and my two sister's and also my mum. my mum and dad are still together which is in a way what makes this more difficult for me. I got engaged just over a week ago and when i saw my dad not only did he not congratulate me but he did not even mention the engagement whatsoever. I am too stubborn to practically have to beg my own father for a congratulations so I ignored it. since then one of my sisters told me that her and my mum were discussing mine and my fiances engagement and he said "they both deserve each other. I don't know who I feel more sorry for". enough is enough and long story short I do not want my dad at my wedding and especially not giving me away. it upsets me so much to even think about it because over the years he has been so cruel. we all know that he is mentally ill but he won't accept help from anyone. and to be honest i can't even see that as an excuse for his behaviour. just don't know what to do because if I don't have him at my wedding then it would start all sorts of arguments within the family.
