ok, so I'm the black sheep here. I say do whatever your gut tells you to do.

My parents are divorced and I only see my real father maybe 1 time a year. I have a WONDERFUL stepdad and decided long before my engagement that my stepdad would be the one to give me away. My real father is an alcoholic and has caused nothing but pain in my life so I cut him out which didn't go over very well with some of the family. A daughter should be able to trust her father to make her wedding the most Beautiful day of her life. You have enough stess with wedding planning and you shouldn't have to worry about your father's behavior.

I did send my real father an invitation but both my Maid of Honor (sister) and the Best Man have strict orders to escort any unruly family members out the door. I also limited the amount of alcohol being served at the wedding.

I hope you have a WONDERFUL day and that everyone will understand that you deserve it and that they should save their issues for another day.
