The two gays in the group ignore it, me and a couple of others just roll our eyes and go along with it. The few that they meet, but m not invited to, probably don't even know that I'd like to see them!
We used to all get together each Xmas for a chums Xmas day, and the group naturally expanded to include new friends, boyfriends, FoFs, etc. S in particular was most out out that it wasn't 'pure' any more, so it got all awkward and they fizzled out. If we invited her and 'outsiders' this would cause huff; if we invited outsiders and not her, that would too. Pfffft. She is, of course, mental, but I find it hard to create boundaries in my head of what behaviour I accept, and hate conflict so don't ever challenge if even if boundaries are crossed.
Anyway. Enough.
