Should i move out of my parents house?!?

I'm 20 and my parents are getting a divorce and they hate the guy I love! my mom hates him and does not want me talking to him at all, yeah they have reason not to like him because we fought a lot (most arguments came from not seeing each-other enough because of my parents) my parents had me at a young age I'm the only Girl, and I've been with him since I was 16! we both have our faults and issues but we are both going to counseling for it, because we want to save the relationship. We broke up once and had a break but we keep coming back to each-other. Help! what should I do i love my family and don't want to have to choose between the two. My mom told me its the family or him, and I'm tottally crushed because I love him even though we had our problems and we both F#*Ked up the relationship we can't stay away from each-other (The problem was not cheating it was always not seeing each other enough and trust issues we are going to counseling for it now) So we are working on making it better but now I dont know what to do! how do I tell my parents mostly mom that i want to do what i want but she cant keep the family from me? should i just move out?
