I have been with my girlfriend for a little over 5 years now. 1 of her best friends is male, I have no problem with this. However he recently invited her to join him to his cousin's wedding. I see a wedding as the kind of social scene where 1 would take their partner, so I'm kind of offended she decided to go.
She says that this guy is like a brother and would never see him as anything else, however I don't know if his intentions are as innocent. He does have other female friends who are not in a relationship so I don't know why he doesnt ask someone else. Also our relationship is going through a bit of a rough patch so I don't think being so close with another guy is helping our relationship.
Has anyone else experienced this or am I being paranoid?
