I am inviting my MOHs family to our wedding. Parents, brother and sister. The sister has been with her boyfriend for a number of years, and my MOH has mentioned that it would be nice if he was invited, but we truly don't even know him well. Plus, we are paying for the wedding ourselves and are already tight on space. We have left out some cousins because we just dont have room for everyone. I feel a lot of pressure from my MOH to invite her sisters boyfriend, do I have to invite him just because they have been together for so long and as my MOH puts it they are a "package deal"? HELP!
