I hooked up with my coworker last summer and finally got the courage on New Years to ask him if he liked me (didn’t have the courage to say I like him). He never responded but it didn’t matter because I went back to college before I saw him again. I’m back now and he won’t talk to me really just the occasional hi. And he avoids me a lot. But he’ll stare from at me from afar a lot I’ve noticed. Why is he doing this?
