honey, it's your wedding....Do what makes you happy! If you want your step-father and mom to walk you down the aisle, they do it! If your father can't handle that, it's his problem not yours! You can't change him and he can't give you want you want/need from him. That's not your fault, it's his fault. It's sucks and I'm really sorry to hear about how he's treated you. It's just wrong.

Don't let him get to you and don't let him ruin your wedding!
