I am getting married in August of this year. I have had a big falling out with my dad a few years ago and things started (I use this term loosely) to get better. By the end of January where things starting going downhill again. Without going into too much detail, my fiancé and I are on the fence of inviting my dad. As of now I do not want him near my wedding but anything can change from now until August. However, this is someone who manages to steal the spotlight. Example: when I called him and told him I had found my wedding dress (at the end of January), he decided to tell me he had started a new relationship and talked about marriage with this new person already and how he wanted to be happy. A week later I found out from social media that they got engaged. I've never met this woman, neither has anyone else in the family, and he mentioned how he wanted to bring her (I've already decided I'm not inviting her because I don't know her).
I feel guilty thinking this way because I know he will be crushed but as of now, his decisions have hurt multiple people in the family as well as myself and as much as I want to be optimistic and think it'll be okay, I have my doubts.
I believe that not having him come will be the best option but I just wanted to hear what others might have to say about this? Any experiences on inviting someone who is known for causing problems? Any regrets not inviting someone who is known to cause problems?
Thanks in advance for your help.
