Revenge is a dish best served cold. become your gf BFF and when the time is right, hit her when she least expect it.

rather than weeping and see ex GF happy , might be as well take a revenge on her.
at least give her some lesson, in the future she will think twice if she wants to do the same shit to others.

u r a an idiot if you choose to kill yourself. the world is so big , so much opportunities to have fun and make money as well to find your dreams.
