What's wrong with me?

St

Been with my bf for over 1 year. We just moved in together. We met at work. Financially I make more than he does so I pay majority of everything which I don't care or mind. He's a good guy, amazing. Very sweet & generous. He's a CNA and in a nurse so we're compassionate people. He NEVER smoked and doesn't care to, drinks rarely/socially, will never do drugs, never cheat. He's way more mature for his age. He's what you'd call an old soul. Just an over all good guy. His family are Caribbean and I can't stand hi pushy and bitchy mother who abused him most of his life growing up. She guilts him into taking care of his siblings & I hate it but he loves his siblings so I stay out of it. We just moved in and she always wants to drop off his sister and babysit. I said no and I didn't want to deal with that because I know how his mother is. She will push & push & push. Plus i don't care for her since she literally kicked him out the house. Anyways, the way I am I know he's amazing but I just been through so much crap in relationships with past men that if we don't work out I wouldn't care if I were single. Don't get e wrong I LOVE THIS MAN. He's amazing but I feel his controlling family is a deal breaker sometimes. He's a total catch so for me to even think about us not being together so nonchalant makes me sad. Why am I like this? I also feel that he could do better in a sense. I'm not very lady like. He had impeccable manners & in the type to burp & fart without caring(I grew up with 4 brothers & no sister) I can be aggressive with people that are rude or just get on my nerves when I'm in a bad mood, I can be snappy. He wants to be the man & stuff and I tend to not listen to him & do my own thing then after I tell him he's right and I should have listened to him all along. He says I'm too independent thinking and should listen to him. Idk I feel sad, what do I do? He's my bestfriend & we've improved in alot of ways in our relationship & i try to listen more but I think he may not be happy because I don't want his family thinking they can just come whenever they want to since they didn't want me at their house and stuff like that. What do I do? Am I just over reacting?
