Trying to move on

Guys, Thank u very much for ur replies as it helped me a lot to come out of a trouble which i thought would never be resolved. Now i hv understood what life is nd i am trying to move on. But, how cn i knw that someone(girl) wants to b close to me ?...I have a dilemma in this regard,

I do understand that this girls flip flop attitude has shaken your confidence at some level but do understand thats not coz of your judgemental abilities going wrong but coz she is confused herself. Your judgement about her was pretty on spot. She had an interest in you which is why she agreed to be your girlfriend. Even when she broke of she came back to you for patch up. That means she was confused about her feelings for you. Then later she decided against the relationship. Which means your judgement was right but she was confused. You will know automatically when a girl gets interested in you. Just keep trusting your instincts, they were not wrong then and will not be wrong in future.
