I met a girl at my university tennis club. We got on extremely well, went out to a club as a part of a social and i tried it with her. Unfortunately she said that she was seeing someone. We remained friends, but a week or so late she said that she broke up with him. I invited her to go out with me and my friends on a night out. We went out and ended up kissing a lot, went back to hers, although nothing happened and i ended up going home early in the morning. Although i was excited about her, i think i was blinded to what was happening. the next day she facebooks me saying that she wants to just be friends because she really likes me but doesnt feel anything for me... that hurt. After a bit of tension, we became friends again, and i sometimes teach her how to improve on her tennis. Recently, I have been involved with someone else but now that has broke down, i wanted to try with her again as she seems like a great girl. I have become a lot more playful, flirty and laid back with her for the last couple of weeks. I asked her out to dinner which she said yes. However, i get a flake message from her yesterday saying that she has to go to her friends birthday. I bust on her a bit and teased her. We then rearranged to meet up the same day but earlier for lunch. I also told her that i dont like flakes.
I feel like im doing the right things now, but that its not working as well as i had hoped. what should i do leading up to meeting her and what should i do when we do meet to try and attract her. Right now im confused. She flirts with me and has fun with me etc. plus i bring value to her through tennis. yet it still feels like im having to try hard to get her, and that she has all the power in the world to reject me.
