Who has no existence and no buddies?

It takes a while to make new friends. It is a skill that is more difficult when we are out of school. These gay men probably just had one thing in common with you - being gay. Helpful but not enough. Instead, try local groups or classes that interest you. You will meet people who share that interest, whatever it is, whether it's pottery, action movies, cosplay, baking, soccer, or whatever.

When you suggest activities with them, start with something related to what brought you together in the first place. Pottery? Try suggesting an outing to an art exhibit or an open air market or a gallery. Action movies? Suggest going to one as a group. Cosplay? Look for geeky ideas like conventions, or just going to a comic book store. Baking? Suggest a visit to some area of town known for its baking (here in Boston there would be a few places; one of those would be Chinatown). Soccer? Suggest a pickup game, or watching a game.

Go slowly. These people are straight, gay, married, young, old, etc. Expand your definition of who you want to be friends with. And recognize that most people will never become close friends with you. And that's all right. There is plenty of value in the group you go to the movies with, but don't expect to lean on them too heavily if there's a death in your family.
