Ok, I don't feel like reading all the pages to this. Being female, here's MY opinion. She keeps you around because you're probably the only dude who shows her that kind of attention. She probably loves the way you look at her. Of COURSE she's gonna act sad when you talk to other females. She doesn't have your undivided attention. She's not stupid. She knows she can fuck other guys, act any type of way, and all she has to do is kiss you or tell you she has feelings for you, and you won't go anywhere. As someone else pointed out - you're her DOOR MAT. Move on or keep getting played.
