For a moment, I thought you were my ex girlfriend and my heartbeat started to rise with every single sentence I have read, but your story went in different direction so, what a freaking relief, you are not my ex! 😛
Well, I think he is still immature and spoiled (not ready for serious relationship), I was like him 4 years ago and with time he’ll realize what he was doing was wrong.
Best advice I can give you in this moment is to cut any connections with him and move on.

With kindness,
Karlo
