does he have a crush on me?

so i have this co-worker that im starting to become friends with. I'm eighteen he's twenty-three... lately ive started to confide in him about how confusing it is to be an adult now and we've been messaging and talking about it a bit. When I told him about some struggles ive been having with my boyfriend he kinda opened up to me saying he had a girl he really cared about and he said i dont know her... I know that he has had a crush on this one girl we both work with for a long time ( I only recently started working there but everyone knows about him having a crush on her), but I know her so he wasnt talking about her... could he have been talking about me? I mean he always gets this dorky smile around me and he messes with me (not super flirtaciously) a lot. What do you think?
