You are such a pathetic loser how could you ever expect to keep a girlfriend!! You don't deserve happiness, you don't deserve sexual attention or any kind of affection at all. You got lucky to get a girlfriend but it did not last long!! She cheated on you with a real man, I'm sure they laughed about it and made fun of how pathetic you are. But she got bored of cheating rather quick and decided the best thing for everyone was to just dump you!! HAHA LOSER.
