Unsupportive parents

My fiancé is active duty and I plan on moving to be with him after the wedding. My family always liked him until they found out that I would be moving away to be with him. Now they’re just negative and nasty. I spent Thanksgiving with him because he had staff duty one of the days so he couldn’t leave. My parents keep commenting on how I abandoned the family and how if I like it so much I should just stay there and not come back. They’ve known I was going up and they didn’t have a problem until I came back. The wedding isn’t for another 6 months so I’m here living with them until then. I work full time and I am going back to school as well so there isn’t money for me to have my own place and I can’t move in with him until we’re married. I just don’t know what to do anymore when it comes to my family. I love them with all my heart. I just wish they wouldn’t push me away with nasty comments and then tell me it’s me who’s hurting them. Any advice?
