Long story short, had a "thing" I think with this guy whom I've developed feelings for. We'd used to talk all the time for 3 weeks and I've met many of his close guy friends. He recently gotten out of a 6 years relationship few months ago though where his ex was the type that was super clingy and jealous and I guess possessive over him? We did hook up and even after we were talking for a week or so but it started getting less and less and now nothing at all. I have to see him tonight because we play on the same sports team and I don't know how to act or what because I miss talking to him and hanging out with him. I feel like I don't exist to him anymore... I really like this guy and I'm trying to move on but I just can't seem to stop thinking about him and hoping he'd text me. I thought giving him space would be helpful but what if he never messages me anymore. We have tons of mutual friends so I'm sure I'll run into him now and then.
