Mother vs boyfriend

Family or boyfriend?
Ok so well my mum & dad don't give me enough freedom. Like I see my boyfriend for about 2 hours each day or sometimes I don't see him at all, anyway my friend came over & we slept over we asked but my mum was asleep so we just stayed over. Anyway I got home and I was in deep crap. They said I'm grounded for a week and the punishment is to do with my boyfriend ? I'm 17 and I can't even stay at my boyfienefd house.  Now I can't even see him for a week & I get a curfew like 9:30 or 10:30 on weekends. Like seriously, I help around the house and stuff. But the other day mum said I'm "fucked in the head" and then after I got home from my boyfriends she said "if you don't like the rules leave" and all this other stuff. My boyfriend doesn't like my mum no more and Won't come over now. I don't blame him. He also organised for me to come live with him? But can my mum make me come home? I still love my mum and family very much. But I much rather stay at my boyfriends. Because he has a job & stuff now. He's moving to wahga soon so i want to be with him or I'll never see him at all.i think my parents are being too over protective. I don't do drugs nor am I pregnant. And I'm also the middle child which I get less. I hardly ever ask for cash. Only for food? And I'm always made to do the cleaning & stuff I dunno what I should do there's so much more. I'm like there target or something, I feel like just leaving and I want to. I will get myself a job and stuff. But can they call the police and make me come home.... And will they hate me because I'm making a choice of leaving...... They say I'm not allowed to do a lot of things, and it's all because I stayed at his house ? What do we do that we don't do already like seriously they surely would no we have sex so what's the matter with staying over. So yeh all this drama because of one night... I'm also sneaking out I never sneak out .... I'm bringing stuff over each night.... What do I do?
