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.
If it makes you uncomfortable, then no. It doesn't make you insecure to feel that way. A girl who is seen with other guys will get the wrong idea and it isn't right for her to do that. She can be friends with her guy-friends, but she should include you when she wants to hang out with them.
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
Women of all ages have nurturing instincts and it appears she wants to help your friend deal with the death of his father. You had the opportunity to spend the night there along with her and perhaps you should have. If the three of you were good friends then no, you should not worry about your girlfriend spending the night at your friend's house.
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.
