Can you 17 get married to your boyfriend 20 you have parental consent but were both on probation?

Ok well i live with my grandmother and and shes very mean to me she beats me and takes all her anger out on me.She doesnt let me see my parents because she says ther white trash and i am too..Shes always putting me down and I've been with my boyfriend for over a year and I've known him for 12 years and my grandmother hates him.She hates all men because no man wants a woman who acts like her.She really crazy.She got custody of me when i was 9 from my mom ,because my mom was in jail at the time and my dad was homeless.So i did a whole bunch of research and found that you can get emancipatied if you get married but the only thing is I'm on juvinile probation and so is he well he's on adult probation and part of my probation is I cant have any contact with anyone on probation...What can i do?
