Normally this wouldnt bother me, my guest list has a guy that I was FWB with in college, but I just get a weird vibe about his relationship with this girl. A few months ago he was cleaning out his wallet and he had a picture of her in there, they only talk when I'm not around, and the girl broke up with her long-term boyfriend a few months ago and has been in contact with my fiancé a lot more telling him she misses him.
I trust my fiancé completely and if he wants this girl there because of their friendship I understand, but I just feel like looking over at our wedding and seeing him talking to her will make me uncomfortable. He says the main reason he wants to invite her is because her brother is one of his best friends so will definitely be invited and he doesnt want her feelings to get hurt if she is left out. Am I being unreasonable?
