Relationships

Hey guys, I have a question. So there is this guy in my math class and like we don’t talk or anything but last night he was talking to my friend and asked for my number which later on in the night he called me but I was asleep when this happened since it was 2 in the morning but like then my friend texted me in the morning saying he asked for my number and them called me cause he has feelings for me I think. And I have his number now but he hasn’t texted so should I text him or just not do anything cause I’m not sure what to do.
