Is this wrong?

So there’s this guy who told me he used

To be interested in me. At the time I was too but I never knew he did too because he’s really goofy and I just couldn’t tell. Anyways he supposedly has a girlfriend or had one, idk he never really talks about her even if they are together. Last night we FaceTimed from 2 to like 6:30AM. I’m kinda interested in him, but if he has a girlfriend than it’s a really big turn off because he should just be open about it. Like when I found out about it and asked him like a month ago he was like “can we please not talk about it “ so the situation sounds kinda sketchy.
