So since I was young I've had this crush on a family friend. Needless to say I turned 18 and we started dating. He's 28. Four months have gone by and he's proposed and I said yes.. but now he's acting different. We fight a lot and he's been going through mood swings. I don't know what to do. It's like he's a totally different person now. I don't want to leave yet I feel like my youth is being taken away from me. I'm helping raise his daughter and I just got my first job while he stays at home. I guess I'm just feeling confused. Any advise?
