My FH went to a family wedding last night (first cousin). I was not invited. While I haven't met this cousin, I've met the mother (FH's aunt). This was not a small affair -- couple hundred people, big hotel, fancy shmancy. I realize this wedding was NOT about me, so I'm going to get over it, lol. But in terms of etiquette, and for my own future reference, shouldn't one invite one's cousin's FI?
