Do i love her or am i just a wimp?

I wanted to break up with her. We were going to break up. Then i see her on skype crying. And i felt like total crap. And i tell her i am sorry. And that i love her. And that i want to be with her. Like i just felt like killing myself when i saw her crying. But its not like i have felt like that when idumped other girls i just didn't care. Did i wimp out? Or is it love? Or what?
