You only cry cuz you never get to hit it.
You need a few more of those to get a backbone and see the light.
If you snap, you might end up being the once upon good guy but now an azzhole cuz it is your turn to hurt some one else's heart.
First lesson, there is no sympathy in a relationship. Here you are hurting and the girl is out there not giving an azz about you so ask yourself, is it fair? Only fair if the both of you hurting but I'll doubt so in your case here.
Your game is weak. You are weaker if you cry about it.
