Wedding Bullshit

So wedding is in like 2 weeks. I'm excited but this shit is getting expensive. It'll be worth it in the end. I'm marrying my best friend and all that jazz.
Here's the thing BD's dad is a douche bag and is not invited to the wedding so he's now given this sob story to that side of the family. The people that said they were coming from his side are now backing out due to feeling "uncomfortable". Seriously what bastard tries to screw with his sons wedding?
My response to the people when they inform us of this decision is "We're sorry you feel that way. We invited who we feel are family or friends. We don't feel comfortable having Brian at the wedding due to his disregard for the sanctity of marriage"
When really I want to say "What ever, if you want to stand behind a lying cheating bastard go for it. We only invited you because we hoped we would get a check." I don't think that would win us any fans though.
