Anyone you regret inviting?

Not sure if this has been asked.
Whether it's a month, 6 months or a year later, is there anyone you wish you just didn't bother inviting?


My boss (at the time). My DH actually is the one who talked me into it, saying it was the right thing to do, blah blah blah. Well, I break and invite the jack-hole. And what do I get? He doesn't even RSVP. I had to ask him several times if he was coming. Then he tells me, he's waiting to hear if this other thing he has is going to happen.
UGH!
