I may be moving out soon, but my problem is that I know my dad will not accept it (my mum is ok with it). Last time when they went on holiday and left me alone in the house for a couple of weeks, I mentioned that I might be going out, and he went crazy. I had to stay in (I didn't, but he doesn't know of course). He always asks where I'm going, and for how long I'll be out. So considering his reaction to me going to the centre of london, I can't imagine what it would be to me moving to another city. I'm 19 now, so I feel like I can take care of myself, other people my age live independently. He is, however, very volatile, he'll get very angry, won't let you speak, and push him enough and he'll kick you, spit in your face several times and push you around, possibly kick you out of the house and then you have to wait by the door for him to calm down.
So how do I approach it? I can't just leave in the middle of the night, that would make such a big mess, I have to at least notify him ahead of time. He sort of sees me as a child he can control though, I don't think he realises that I no longer legally need his consent.
