He might be gay. Try and chat him up to see.
Solve her problem
i seriously am worried...😭
yes id be worried. Best to have a serious talk.
yes. it means she is a lesbian.
not really they could just be busy
you should apoligize t your friend and his girlfriend
nope. she is observing you.
If you two are genuine friends & nothing more, yes. There should not be an issue. Just remember to be respectful of his relationship & his girlfriend.
get to know them better
if there your real friends then they would be supportive of your relationship, and you shouldn't let your friends make fun of you girlfriend. remind them who has the girlfriend around here, And maybe they should get a girlfriend. But if you tell them to stop and they won't then forget them.
it depends how well and how long they have known each other. You should first think to trust your girlfriend no matter what, but if they haven't known each other for that long, there is probably something wrong. If they are not that well of friends, or are just "friends" then I would say there is something wrong, and it is weird that she did not ask you.
