Quote of the month: "Remember brick walls let us show our dedication. They are there to separate us from the people who don't really want to achieve their childhood dreams
"~ Randy Pausch
If she is with someone else, it sounds like you are out of luck, so you are asking the wrong question. You should be asking "how do I get over losing the love of my life?"
You really shouldn't try to get her back. If she did it once she would do it again. Chances are she doens't feel the same way about you as she felt before and is happy with whoever she is with. If you had her back, could you both live with each other without her feeling guilty and could you completely forget about what happened?
You really should concentrate on getting over her.
it takes time, with time you will get over her... we are all fighting the same battle, i know what ur going through, its tough but it has to be done... try to avoid contact...
