Mh...I had a love problem in the near past, too.
My ex girlfriend told me that she doesn't love me anymore...what is a bit harder than your problem, trust me.
Well, after two days of crying, I "came back to life".
Just try to forget her(what I did, but it wasn't a real success).
Talk to a good friend you can trust and tell him everything, really everything you feel.
There are lots of other girls on this world . And everyone has the right to be loved.
€: @Pic: She isn't a girl for a long relationship, I think.
