up until recently i wasnt one to recommend the hit it and quit it plan. you need to understand that most women are lying thieving whores and should be treated accordingly until proven otherwise (especially if they are under say... 25). heres what i did, double bag, rock on, and run screaming into the night waving your pants over your head so you can be sure all her neighbors both hear and see you.

she'll never admit she lied or she was wrong (unless she wants something), the only way to save face is to walk away and dont say anything. she probably wont talk shit about you for fear you'll say something true about her.
