Is it weird for me to ask him out?

Ok so for some context, there's this guy i like who i have one class with. At the beginning of the year he asked me out but i (regrettably) rejected him because i was seriously questioning my sexuality and thought i was gay. It was pretty awkward and i just ran away after he asked me and now, a couple
months later i really regret it because i actually like him a lot. Is it okay for me to ask him out and apologize? Or is it best to just not say anything?
