Let me start off by saying that my fiance and I DO NOT have a good relationship with the majority of his family. We don't speak to his mother or sister or the vast majority of the extended family due to issues that came up surrounding the death of his father. He has one sister that we still speak to, but she and I did not have a relationship ourselves until the last few months (when FH told her he was proposing to me she tried to talk him out of it). I've worked hard to build a relationship with her as I know that he has lost most of his family.
She called him yesterday and freaked out that a) we're not inviting most of the family, and b) that she is not in the wedding. As previously stated, she and I just got on good terms a few months ago and my bridal party was picked out last July (our wedding is in October). The rest of his family does not like me and we don't speak.
I want to know how everyone else would handle this. For the sake of saving a relationship, I think we're going to invite her and also invite both of my brothers to be groomsmen. But I don't love that we're being manipulated into doing so. FH is angry with her and wants to just leave it as-is...but the soft spot in me just wants to avoid future issues. Thoughts?
