Okay, stop being stupid.
How many times do we have to say this?
DON'T FUKING TALK TO HER.
Even if she texts you, DON'T RESPOND.
Don't act all aloof
In fact, screw "ganji games" at this point. You need to take her out of your life, which, it seems she's already done for you. She, the woman, had to man up and drop you because SHE FELT SORRY FOR YOU.
Go out man, find yourself, build your confidence. I don't care if you've been with 8 or 1000 women in the past year, GO FIND OTHER GIRLS. It really seems like you have no life if all you're doing all day is thinking about this girl.
Get out some brah. Right now, it seems like PoF will only hurt you. What you need is a full weekend of just getting out in public and meeting new people. Soon, you'll realize that no one girl is worth this, because there's literally millions more out there just waiting for you.
