Most Helpful Guy
Sounds vaguely excuse-ish to me. I think he was looking for a reason and pulled that one out of the hat. I know it isn't a good feeling - but in this case, I'm not sure what you could do other than what you did. He seems to be the one who wants to move on, and you can't force a relationship.

"You're not good enough for me", so in the beginning he was trying to make it seem like he wasn't good enough for you and then he switched it around, sounds really asshole of him or he just wants to be an asshole so you're not as heart broken but here's the thing people will be just up set either way. So I would just let him go, if he's able to let you go that easily then let him because you deserve more.
