Ok so my mum met somebody on a dating website about a month or 2 ago now. 

She is very very close to him, he's always with her every single day, they have photos all around the house together she never seems to bother with me anymore since he's been around. She says to me he's her soul mate and they're going to get married. To me this is all going a bit quickly. They think they know everything about each other, which ok that's fair enough if they are happy then fine. But since the first day I met him, there was something about him. So I gave him a few more chances, he seemed meh alright but still I can tell when there is something about someone.. my boyfriend met him, he said to me he's ok but a bit strange. My brother met him, he said to me it's all moving too quickly. 

(Quickly going to say He was in crime watch because on a night out in 2001 he got beat up and left dead and had to have brain surgery) so he's part time work because of it.

Anyway, last night me him and my mum went off to the pub for a drink or 2. Ended up staying for quite a while. I thought oh he's actually quite nice I'm getting to like him a bit. Suddenly everything seems to kick off, my mum said to me we're going home now and I was joking about with my mum as I always do like no mum I'm staying here. He got in my face and shouted "stop acting like a silly little C****" 

I was absolutely gob smacked, I started crying and my mum and him dissapeared and left me at the pub by myself. I am disgusted in my mum for choosing someone she's known for that long over her daughter. She rang me up when she got home and he's shouting abusive language at me over the phone still calling me names. 

Now I just leave it, I hung up and I don't know what to do or think. Maybe he's controlling my mum? Maybe he's effected by what happened to him. I just don't know! 

Update:

So yeah two months later he's still in the picture, I still don't like him, he's trying to now engage my mum when they've only been together for 2/3 months ... nothing's going to change he's still going to be an ass hole. He knows I don't like him and I never really see my mum a lot now . Thanks a lot to my mums boyfriend!
