my guy friend came to stay with me for a few days and then stopped talking to me after he left?

i’m confused and anxious about this situation. the night before he left, we went out and got pretty wasted. then the next morning we said bye and all was good. but since he left he’s stopped replying to my texts, but he still likes my stories. i feel like i’ve done something wrong, and want to ask. but i don’t want to be annoying. should i bother or just leave him alone?
