Not at all. There's some history, but I'll keep it as short as I can.
I met him a little less than 2 years ago at uni, and after a few months of talking with him, I eventually asked him on a date. He immediately turned me down and said he had to focus on schoolwork. We ran into each other the next week; I apologized if I made him uncomfortable, he told me not to worry about it. Winter break passes, and I send him a text to ask how he was doing. After a little chat, I suggest we hang out sometime. He says okay and the conversation ended there; but a few minutes after goodbye, he sends me a text saying he's not gay. I tell him that's fine and I'd like to be friends, and he says he's fine with that.
Now, we've both graduated, and I've hung out with him a few times. I enjoy hanging out with him for the most part. He responds to my messages, and he can be engaging; but there's just no consistency in his behavior. Half the time, he's really cool, talkative, and easy-going; the other half, he's skittish, distant, and says hardly anything.
I'm sure none of this is a big deal, but this swing in behavior is just really confusing; especially since I know that if he's not gay, he at least uses tinder to check out other guys.
