Issues in our relationship/Long rant

I have been with my fiance for almost 7 years. We have a baby and recently got engaged. Theres been issues with his family where he puts them over me. Like there was evidence that his sister took my clothes twice and he took her side. Where his mom was being rude to me and tried to run our home and I told her that she hurt my feelings and it turned for the worse. I was never disrespectful to her. I just wanted to let her know how I feel. It bothered him because he said his mom didn't mean it that way and she comes off rude. But thats ok if you accept it, I don't like to be treated that way. And hes just been too much where he gets easily annoyed with me and I don't feel like I can do what I want, how I want in our home. I take car of our child, and him. Of something isn't done his way or if I dropped something on accident. It bothers him. There is more but basically I think I messed up in trying to explain to him how he makes me feel and how he treats me. I mention to him that I never see him talking to his family or friends that way. And he just told me right now that he's sick of hearing that and that I'm not his family and he will not treat me the same as them. Now I know he says things out of anger but I find some truth in that because be doesn't treat me like everyone else.
