As the poster of this thread, I thought I'd share my experience of worse dating attempt.
Four years ago, a time when I was a little more naive socially then I am now. I met a girl at a club, we danced, and she showed strong interest and attraction towards me. I was excited, we exchanged numbers, decided to give her a ride home, and we ended up hanging out all the time almost everyday after that. We were actually close friends for almost two years, and I spent that whole time being friends with her and put up with a lot bull crap because hopped I could eventually get into a relationship with her. We never did though and the course of this two year friendship was a none stop cycle of hope and disappointment. The worse part about it was after a year or so, it eventually downed on me that she was using me, and manipulating me into thinking that she like me to she could get what she wanted. She asked me for rides almost on a daily basis, didn't pay me gas, asked me to buy her things like cigarettes, give her food from my house, borrow tuns of money and not pay me back (and got mad at me when I asked to pay me back), and even (in a flirting way) talked me into taking me on drug runs so she could get drugs and would tell me she would have sex with me if I would but never would. The drugs runs were pretty nerve wracking situations and I'm glad I never got in trouble doing that. If I said no when she asked me things, she would then say I'm not caring and not being a good friend. Even worse, she always talked down to me, yelled at me for how I drove, was mean, criticized my insecurities, social struggles, and often shhhed at me when I talked but she always ranted about her problems to me. She always flirted with other guys in front of me and when ever she slept with other guys she would always tell me, and then yell at me if I appeared jealous. You might ask why did I put up with this? Well she was very tricky, she was really good at tricking me into thinking she was a good person at heart that was only struggling through a few issues. She also was good at tricking me into thinking she was falling in love with me, and about to have sex. She would say how she was always there for me and her other friends. She would then slip hidden attacks at me, use me, and drain my energy leaving me with nothing, almost getting arrested, and still under the illusion that she was a good hearted person. What made it even more confusing was that she did treat other people nice, and did a lot of things for them. In fact she usually did a lot more for other people then me. I often got really upset when I saw her go out of her way to do things for other people but nothing for me after doing a lot for her. After having my mind played, after feeling sad about thinking I messed up somewhere in not getting a relationship with her, after thinking she was a good person, I finally realized she wasn't and probably a narcissist and I got fed up. I finally ended the friendship by writing a letter to a boyfriend she just started getting into a relationship with and told him everything. She of course found, got really mad, and cut me out of her life.
