I agree... I think >>1 is the type of guy who would get bored with a girl -- pretty or not, interesting or not... I am that kind of guy. Instead of wandering through relationships, maybe it's time for you to step on your toe, give yourself a slap and then a nice hug and then try to do some fun things with her. Give her a chance cause it seems she loves you. If even after that you don't feel love then you should really free her...
Good luck.
