Move on without losing hope?

My boyfriend broke up with me this past week. He said he isn't happy with his life, he's not working, and he's "gonna fix it damn it" It was a cordial break up, and while it's really hard and it hurts, I'm doing better than I have in past break ups. I havn't really accepted that it's completely over yet and I think that's why I haven't totally broke down. I know everyone says it when they break up but I just knwo we're right together and good for each other.
He said "If he feels on top again and wants a girlfriend, I'm the first and only on the list."
Then he texted me 2 days after we broke up to see how I was holding up. I texted back that I was manaaging and thanks for asking. THat's all. NC otherwise.
So, questions is: does it ever happen? Might a guy come back once he gets on his feet? Am I just crazy for thinking he might? THey say if you love someone to let them go, if they come back they were always yours and if they don't they never word. I guess I don't know how to move on without totally giving up hope...any suggestions? Similar stories?

yeah, maybe he wasn't where he expected himself to be in life, and having a girlfriend would distract him from getting to where he wants to be. It is possible he will go back to you, but don't dwell over it; live your life and don't restrict yourself if you meet a nice guy...'cause trust me he wont restrict himself if he meets a nice girl.

Why be with someone that has to break up because they can't cope. A relationship is a partnership. You are supposed to turn to each other for support through thick and thin....it's a test before marriage. If he can't depend on you for support, or he doesn't think having you in his life is important enough to help through bad times, then it was all for the best. A marriage with this guy would be disastrous.
