Is it normal to be unsure if someone is into you or hates you?
I genuinely can't tell if one of my coworkers has a crush on me or hates me and wants me to stay the fuck away (even though I'm pretty quiet and rarely talk to him).
This guy is generally known as an awkward bachelor, but he's very funny and sociable with everyone (men and women alike) except me. He doesn't speak to me unless I ask him a question, in which case I might get a short answer. He seems to avoid looking me in the eye. It's been like this since my first day, so I don't think I could have offended him. We had to work alone together on a project and at first he barely spoke to me, but after a while he'd initiate some low-level chit chat. He smiles at the jokes I make, but I'm not sure if he's laughing with or at me...
We haven't worked together directly for a while, so he's gone back to being very reserved around me - if we're about to pass each other in the halls he looks at the ground and steps out of his way to avoid walking too close to me. I've sat near him at lunch and he goes from having a lively conversation with someone else to being completely silent and staring at his plate. I saw him at the bar recently and he yelled hi to me, which I took as a friendly gesture, but when I tried to talk to him the next morning he was extremely awkward.
I'm not really sure how to proceed - I'm being transferred to another department in a few weeks, and if he dislikes me I can just avoid interacting with him until then. If he's interested but just extremely shy and awkward, I'd pursue it.
