HELP!! Relationship advice!!

So, I'm tired of being at home. I'm living at home and can't afford my own apartment. My bf is stationed at fort Campbell, if we were to get married I could move down with him, and still take online classes at the college here in town which I've already been accepted to. I just need out. Out from under my mother but I'm 19. She wouldn't be a fan of this idea at all. But I want it.
