@rom828 - I am divorced also. My kid didn’t want to invite their dad’s SO to the wedding and he wasn’t too happy about it. I was concerned it would be awkward, but both of us walked her down the aisle, everyone was on their best behavior and everything went off without any drama. I did everything I could to be pleasant, which included keeping any negativity out whenever I had to interact with my ex because it was all about my D that weekend. I think if your ex were to come, mostly likely he will behave and be there for your daughter. I was very apprehensive before the wedding, so I know how you feel.
