Can it be considered love or just heart ache?

You say 'we' broke up like you both wanted it and he just moved on but you are stuck. How much do you think he really cared if he could move on like that? You may be better off in the long run without him but it's getting there that is always hard. Someone who breaks up with you by not facing you is a coward for that's pretty low to do that. Give it time and you will be fine.
