First Visit in 5 Years

My parents separated and eventually divorced when I was 17 and my relationship with my mother deteriorated to the point where I didn't want to speak to her at all and I moved out of state to live with my dad. We started talking again a few months ago because I'm getting married and I thought it through very carefully and I've decided that I want to go see her. I'm a little nervous because it's been 5 years and I don't know what to expect. I want to repair our relationship because I want her to be a part of my life again because it's changing so much and a lot of exciting things are going on. Any tips?
