so i went to school with this girl and she was talking to my friend so wehn they stopped talking so i talked to her & i got her number(which she mostly barely even returned texts or call) and we were talking for a little while but then i found out she was a playette than she got a secret bf which everyone found out about than when they broke up and she keep shit testing me and then i try to approach the situation nonchalantly it kinda got her to always stare at me and say off the wall shit like lets fuck so everytime i saw her i didnt try to do what i think all the other dudes did and just go up to her and say how beautiful she was and be all on her dick(so to speak) i just walked pass i say hi when she did which i thought would work but know school is over she graduated and we still message and stuf. i think the only reason i persuate her is because i like a challenge but i cant seem to crack this one.i just need advice on dealing with females like this what to say & or do any advice would be incredibly helpful & appreciated?

Hey bud, I know how that feels when you wait for your chance for a girl and it let's you down. I'm not the only one that's going to tell you this but they're so many other women worth your time. This girl like the one I chased after before I found out she was a mistake had already forgot about you. And just like me you need to forget about her man. She had her chance with you, now show her the mistake she made.
Eat. Sleep. Sarge.

im sorta making her sound uninterested in me but she totally is its just her acting like that & i know how that sounds but its true

I feel you man, but you have options in life and trying something new is almost always the path that pays off.
Good luck bud
