Hey guys whats up, so long story short i have been sleeping with this girl for +-6 months (she is actually the love of my lifes' sister, but thats another story for another day!). She recently went away for a month, and while she was away she asked me if i had hooked up with anyone. I have a no lying policy (unless she asks how many girls i have slept with), and so i admitted i had hooked up with other girls! She got back over the weekend, we hooked up and slept together. Now 2 days later, she has ended things with me
Basically she cant handle the fact that I have no intentions of things progressing at the moment and that I hook up with other girls while we are together, even though I made my intentions clear to her from the start. I recently attended an Adam Lyons bootcamp where he explained that this is a common phenomenon! He also mentioned various things to say to a girl in this very situation, that will enhance your chances of sleeping with her for another 6 months. I didnt write these things down and cant remember!

haha
I am not just using her for sex, we have an amazing connection and I do have emotions towards her. I am currently on an incredible journey in the PUA world and for selfish reasons have chosen not to date her. Please guys your help as to what to say to her would be much appreciated!
Peace and love
