Being a "best friend" with a girl for 3 years. But two months ago, i started to improve myself to another level, gaining more knowledge, hit the gym...Her attitude to me was raddically different, she started to have more physical contact to me like arm in arm or trying to touch or lean on me... But i'm in the "push" mode, don't really care about her as i used to, spend more tine talking to other girls, but sometimes i still pull her a little bit which makes she feel grateful. What should i do now to get a relationship with her?
