I'm getting married and I've completely cut my dad off and he's not getting invited.
Why don't you want your dad involved?
I want to show him that I didn't need him in the first place.
Have you tried repairing the relationship with your father? Do you think he might want to support you in an important moment in your life?
I don't really care I am going to have a new baby soon anyways.
I think you might regret not having him there one day after he is gone even if you don't see eye to eye right now. I think family is the most important thing and trying to work on a relationship is worth it.
