While I was growing up, my father was addicted to meth along with being inprisoned numerous times and being abusive. He has been an embarrassment to me my entire life and now he is married to a drug addict that has 5 children and one on the way, needless to say, i'm not fond of either on of them or their insane children. I saw my father literally skip his sister down the isle to be married by their father. It left her mortified and it would leave me the same way. I do not want to invite my father or his wife but this means i wouldn't be able to invite his side of the family because my father, who is an aggressive and beligerent person, who show up univited and make the worst scene ending in arrest of not only himself but more than likely my fiance and his father after they see to my father. I'm unsure as to what i should do. My step-father has been there for me since I was just ten years old and he has been a father figure to me. I want him to walk me down the aisle but yet again, i am just scared of my father's reaction. What should I do? and may i add that i haven't spoken to my father in several months after he grabbed me by the throat in his front yard and he hates my finace and his family.
