Does he like me?

Hello. I could just be totally wrong(I probably am) but I have a feeling that this guy might like me which is weird for me to say because I’ve never believed that anyone would ever have a crush on me because of my very low self esteem. He always make direct eye contact with me. He never looks away I’m always the first to look away. Like today he asked me for help saying that his friend needed help(they were working in a group) so I tell the other guy that I don’t know and I just look back at him and we just make eye contact. Until I turn away and break it. Then a couple of minutes later he compliments that he liked the tee shirt that I was wearing. And I said thanks and again we make eye contact for a while until I look away. And lastly I turned around towards his direction and I can’t remember if he was already looking at me but we just looked at each other. Not saying a word. So I felt a little awkward and nodded my head. He nodded back then he still wouldn’t look away so I waved and he waved. He still didn’t look away so I just kind of smiled and looked away. Idk if he likes me or if I’m just crazy. What do you guys think?
