Very long story short, my fiance played match-maker with his friend and my sister. After a few years of torture it finally ended (she broke it off with him but was heartbroken). Am I being totally out of line by not wanting him at the wedding? My fiance isn't pressuring me to invite him, though he says it is one of his good friends. My family and I can't stand the guy for how he treated my sister and I don't want our ill will toward him to ruin the day. Am I being unreasonable?
