What I think is that it's your classic young love relationship. She gave him multiple chances, but he had too much fun at a bar and ended up cheating on her. She broke up with him, and he's a little upset but realizes it's over and he doesn't want her coming back to him crying. Sounds like he's tired of how easily she gets hurt (from other stuff) "One cut is all you ever need, I don't want this anymore".
