I should just text him right?

So about a month ago I got out of college. For most of the semester I’ve become decently close with a guy. My friends are convinced that he likes me because of how often he would message me random questions about the class we shared and because he came to our door drunk one night (don’t worry its not stalkery, we were neighbors) he came twice that night actually.

I just don’t know if it’s an attraction thing or just cultural differences making me draw connections that aren’t there.

We’ve talked once shortly after we left but I don’t want to be annoying if he’s busy. Should I just do it or wait a little longer?

I just get super anxious when it comes to guys

EDIT: thank you for the comments, i think I text him later. I don’t know if hanging out is possible right now because he’s out of state working all summer but I’ll definitely ask him
