He wasn't that invested in you in the first place
Sometimes, men will spend time with a woman with no real intention of ever having a long term relationship with her. In those cases, when your time is up, it’s up. The relationship was never going anywhere anyway, and you’re better off without him. Sometimes it’s not because of how you are, what you said or what you did. It’s just where his head is at — or is NOT at, more importantly.
