its ok, cheer up. everybody has relationship problems at one point or another. you may feel this way now, but eventually, you won't. and youll look back and laugh. (i look back on similar situations from my life and laugh now) the best thing for you to do is probably to just let it be. still talk to her, if you typically talk to her and stuff like that. if you love her so much, you would probably still want to be around her, whether you guys were together or not, am i right? after a while, either you guys will just end up close friends, or else youll drift apart, which is a lot less hurtful than just stopping all contact.

hope i helped a little, and best of luck.
