I think I'm just looking for validation that I'm not a awful person here, but if you think I'm wrong, that'd be helpful too.
FI's twin brother is getting married a month before us. FMIL put together a guest list for them, which included everyone on their side of the family and also FMIL and FFIL's friends that they'd like to see invited. As far as I know, everyone who was put on that list got invited to FBIL's wedding.
We took that same guest list (conveniently already put together - yay!) and used it for our wedding. However...FI balked at a couple of his parents' friends. He was fine with the first three couples, who are around fairly often and who sometimes did joint family events with them all when he was growing up. But the fourth couple? He's met the husband exactly once and the wife never. He (and, to be fair, I) have no interest in people being there who we BOTH have to be introduced to. Especially since it's only 100 guests as is.
The thing is...I'm feeling guilty about this. I feel like we have no responsibility, etiquette-wise, to invite this couple. We don't know them, and FI's parents aren't hosting the wedding, so that issue's not in play here. But I feel like we're going to hurt their feelings by comparison. "The rest of Joe and Sally's friends were invited...and we're not." AND..".a month ago we were invited to Joe's first son's wedding...but not this one. And everyone else is."
If it were up to me, I'd probably just throw them onto the invite list to play it safe. But FI feels pretty strongly about this, so I don't want to demand that if I'm just being overly sensitive. So what do you think? Am I overthinking this?
