A couple of years ago my grandpa and I had a falling out and have not spoken since. I have no interest or intentions of inviting him to the wedding. When I was putting together my guest list I did add his brothers and sister and parents. But the more I think about it he only has one brother I'm close with, the rest I couldn't tell you the last time I saw them nor do I really care much for them. My family wasn't invited to any of their children's weddings. Basically, my question is this: if I invite the uncle that I'm close with and my great-grandparents, am I obligated to invite the rest? I doubt they'd show anyway, but regardless...
