AITA for cutting my mom and step dad off

Going to try and make this long story short

Ok, so, when my wife and I were dating, everyone loved her and were kind. Then, when I proposed, things changed. They (mom and step dad and a few "friends") began to be rude to her when I wasn't around. She would tell me about it, then one night, I caught them being rude/mean to her and told them to knock it off, that shes here to stay. Well, fast forward and 4 months before our wedding, my step father came over and asked if we could talk. He would not even make eye contact or acknowledge my soon to be wife. He said that I wouldn't get the land I'm supposed to inherit if she doesn't sign a prenupt, and that they will not be at the wedding. I said, who are you to tell me what I'm not going to inherit, your a step dad and that she is not signing a prenupt. And if thats how they feel, we don't want them at our wedding anyways. We were also going to have the wedding there on the land bc there is a beautiful spot. Well...we had to find a new place quickly. We did and it was perfect. Well...its the wedding day. Guess who shows up. My mom and step dad were already wasted, they were dressed like it wasn't a special occasion. Wearing jeans and tshirts. I told them they weren't invited, but they rode with someone who was. I had them sit in the back and told them not to say a word. Thank God for my brother and dad, who kept an eye on them. My mom calls me a few weeks later like nothing has happened. I told her that I was extremely disappointed in them, what her husband had said before our wedding. She acted like she didn't know, which was a lie. Fast forward to now, I haven't spoken to them for at least a year now. I honestly don't know how long its been. Still happily married. AITA for cutting them off?
