For you Snake Eater, trust me as hard as this sounds, you will get over her. Maybe even end up hating her on how she treated you afterwards. This is what happened to me, after a month and a half of being major depressed, I finally had the ***** to say 'Enough is enough' and let her go. In fact I am actually starting to like this other girl, sure she doesn't collect but she is at least extremely nice and caring.
So really all I have to say to both of you is that it will get better, no matter how hard it seems to move on or to hope that something will happen you must purist and move forward. Like Dr. Ian Malcolm always says...
