If you ended on good terms, then you can at least count on keeping him as a friend. Maybe if your lives change in the future (like having a less-demanding work schedule), the two of you can give it another shot.

I'm sorry that the relationship had to end. I hate break-ups. I hope you are able to take some time to yourself to "mourn" the loss, and make peace with it. I've often made the mistake of not giving myself the time and space to reflect on things, feel the pain or regret (or whatever), and then move on. I hope you don't make the same mistake that I did (and cause yourself more pain than necessary).

Maybe you should schedule a girl's night? A little time with some close friends can be very helpful after a break-up (in my experience).
