Lol please don't tell me you believed what she said
girls who are sluts will go home with you the minute you k-close them. I think she knows her way in some form of game. So now you are talking a few months ago, if she was a slut then it means she def slept with at least 2 guys, so it's kinda late to fix things. When you saw her at the party you IGNORED HER. Girls don't like to be ignored and if you ignore them then they'll ignore you too, especially that you've exchanged eye contact! So this is kind of a game over with this girl unless you pump into her next time.. Here's what you need to do next time you see her.... Approach that bitch and tell oh so i see you've changed 'you look different from when i last saw, with that look on your face that would make her think that she gone from good to bad' Then she's gona ask you what do you mean? in a good or a bad way? that way she'll become curious. Play your game right then......... Until then, find another girl, even if she was a HB7 because common man, you hardly find a HB10 unless she's a model
