family issues

Okay so my dad is really secretive about things and sometimes I'm in bed around 3pm and he just walks in and gets in bed with me and starts touching me and I hate it I cry all the time because of it and now I've got a boyfriend I keep to myself a lot so I normal don't go downstairs so when he come upstairs again he will shout me and tell me to get in his bed and he will just start feeling me up I hate it and idk what to do because if I tell the police he will probably go to prison but my mum is 56 and she's disabled and can't work I can't work either school and I'm just generally upset about him touching me and I can't trust anyone so idk what to do 😞
