Help me with this guy's behaviour?

I've been in the same university class with this guy since semester one, but I didn't notice him until we were in our third year, conducting our mandatory non-academic activities.

We were suddenly grouped together. He then HMU on Teams, and ever since, he's been texting me on messenger almost every night as if we've known each other for a long time although we haven't.

He was never missed with good mornings, good nights, or a few flirting jabs from him. Which making it more complicated for me

To be honest, I'm afraid of guys who I can't read, just as I'm worried of myself since I'm the type of person who can readily pick up on feelings that eventually can hurt me later on.

I've that dilemma where as a member of my university's student body and I also participate in the " find a friend to talk to" campus program, my peers do come to me to talk about their problems and those were just mere helping out others. But his situation is currently just complicated for me

I don't want my feelings crushed because of my own expectations, but I can't ignore the fact that someone needs my help or at the very least my presence as a listener.
