Also, who cares? Don't feel guilty. That's pointless. It's not helping either of you. They were just being over-emotional; I highly doubt you broke any hearts. Crying didn't help either of you, either. You should both avoid doing pointless things and get on with your lives. The more you sit here whining over how you feel guilty about something that's already done, the higher the chances of you missing out on something better are.
Guilt = Stupid Emotion
You didn't do anything wrong, so just get over it. They'll get over it soon, too, and then you'll be sitting here, still guilty, feeling like a dumbass.
