Was this out of the blue? I guess it always seems like that when you are the dumpee, but even you should pick up on whether he is lovey dovey anymore, communicates to you, if fighting has increased, etc.
It's amazing how we don't take the importance of breakups to heart. It's almost like it's part of every relationship and everybody goes through it. You shouldn't view this as a cycle and that he will just magically come back. He might if he doesn't have what he is looking for and gives into lonliness. But you break up when you want it to be over.
Take a good look at the relationship and if he comes back begging, think about it. Begging isn't attractive and would you want to take him back out of guilt or because you still love them?
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
