A couple of times acquaintances or people I thought were friends who are classmates or people I have worked with have not invited me to things. They haven't forgotten. They have just deliberately left me out. When I asked people who were invited why I was one of the only people not invited, they said the host didn't invite me because I didn't get along with someone who was going. A few of my friends (who don't know these people) said it was just an excuse and they probably just didn't want me there.
AIBU to think this could just be an excuse? What does everyone else think?
