Just looking for some advice. Sorry for the length.
A month ago my parents had been drinking and got into a fight. I'm not sure of the exact circumstances and I don't really care because I make a point of staying out of their arguments.
What I do know is my mum was left with a broken nose, which he did with a glass bottle, a burst lip, burns on her skin from where he stubbed a cigarette out on her, and bruises all over which made it hard for her to move for a few days. He also strangled her, spat in her face and verbally abused her.
My dad has no injuries. My mum said she just tried to defend herself the whole time and he overpowered her. Regardless of whether or not that's true, there's no excuse for inflicting those injuries on your wife (or anybody!) and I'm disgusted by my dad's actions.
I'm the only person my mother has told and she's made me swear not to tell anyone, even my partner. She's lied to everyone else about how she got her injuries.
And this is where I need advice... It's been a month now and I haven't spoken to my dad at all since before it happened. I just don't know what to say and I hate confrontation, but I don't want to act like everything is fine and like I'm not horrified by what he's done. I don't want to carry on like nothing has happened or let him think his behaviour is acceptable, but I don't want to lose my relationship with him either. He's made no attempt to contact me either. My mum says he's avoiding me because he 'thinks I hate him'. I don't see my family much because I don't live that close, but on the 2 occasions I've visited, he's faked illness so he wouldn't have to see me.
My parents are trying to patch things up between them, and in a few days they will be visiting me. I have no idea how to act around him, or what to say about it, if anything. I don't want to make things more difficult, but I don't know how I can just play happy families knowing what he did. Any advice?
