I had a similar experience. I've known a girl over the last few years and in that period she has put me into the friend zone (the one without benefits) and is now kissing other guys infont of me e.g. on my birthday night out. Personally I find it hard to see that in front of me. I cant even call her babe anymore. It has to be buddy or something like that. In my opinion, the more you have sex with a girl. The more attached or needy you become to her. Especially if you get on well and see her over a period of time. If she then decides to be just friends, the attraction is dead and the only thing you cab do is call her mate a lot and go with other girls infont of her. See how she likes it when you do the same. Cuz after all WERE JUST FRIENDS, RIGHT?!

Then try to be the fun non needy guy that she was attracted to in the first place. It's only when you are doing well and not caring that you will do better.
