Morgan Wallen - 865 Lyrics Meaning

He is trying to get over a girl by drinking, but every time that he tries to drink, he is just reminded of what he used to have and what he is craving to have back. He doesn't want to bother the girl that he once had but he couldn't help but bother her because of what he misses. It was a bad breakup and he wanted to give her space but every time he tries to drink to get her off his mind, he doesn't know if he still loves her but he also doesn't know how to interpret his feelings right now because of all of the emotions that he's having right now.
