I can't stand my family

Mom had different boyfirends when I was growing up, and a Fiance at one point who was not the nicest guy (He hated me and blammed all of their relationship problems on me. He moved out and after that my relationship with Mom went down hill fast. I think she blammed me in some way for the relationship not working out. She got physically and emotionally abusive toward me to the point where she would end up calling the police because we were fighting. This was around the time where I was a Junior in HS. This fits of hers happened alot and she ended up taking me to court 3 times for assault and battery. I was the one who had scratches etc.. all over me, but she was one who called police. At one point, I came home from school and my key did not work in the door of our house,she had changed the locks when I was at school. She packed up my entire room into boxes and left me a cryptic not on the front door telling me that I can come back another time to pick up my stuff and that I was not welcome to live there anymore. Lucky for me I had friends who I could stay with. I had to wear the same clothes to school for 3 days until she decided to let me in the house to get my stuff. I ended up living with friends for a year after that. Mom ended up moving to another town and told me I could come back and live with her. I was not a bad kid at all but I was a teenager. I went back and started going to College and working FT. Eventually I moved out and in with my BF now Fiance. I am not super close with Mom, although she has tried to re-build our relationship. She has also apologized for all the stuff that happend when I was younger and I forgave her, but I feel like I said it to make her happy. I do not think that I actually forgave her in my heart, I don't think I ever can. I told her that I got engaged and she told me that I should reconcile with her family so they can come to my wedding etc…
I have not seen her family in about 5 years, as I am not interested in being a part of their lives. I think it is because they were not around for me when I was dealing with the abuse from my mother, I only had my friends and their families. Mom did not even bother to ask me what I wanted to do for my wedding etc…. I am not planning on a normal wedding etc… It makes me really angry that Mom does not ever inquire about my feelings or what I want, I barely remember her ever even telling me that she was proud of me for anything. Mom wonders why we cannot have a close relationship. I am, now 31 years old and still have these feelings about her and her family. I am really not interested in her or her family, people say I “should get over it”, but I strongly disagree. Am I normal for feeling this way?
