egaaah...You sound pretty young, especially since you broke with her over the phone. Next time, do it person. But if you are as young as I expect, your relationship with her wasn't going to last forever anyway.
It seems to me you like the tomboy better since you decided to dump your girlfriend. I think that was better than the way-and-see approach, making your ex seem like a backup. Clingy relationships are hard (though I did notice on one of your complaints about phone calls...YOU CALLED HER) and I personalyl prefer tomboys over girly-girls.
