Hi, if you want advice from a woman, and i am accountant as well

First think about this,that the women we like to flirt with a lot of man that we do not find attractive,but we just flirt them to see if thay catch the hook,and for our self confidence.So we don't know if she likes you.
Sorry to tell you that.
But when a woman really likes a man she don't mind to be close to him,if you touch her hand by accident when you give her some documents,or you are close to her ,and she don't make distance this is the good sign.
If you are brave ask her out.If you want to make more slowly approach find her on facebook and chat there slowly slowly to break the ice ,or with messages,but this will put your ranking down ,the Alfa that knows a woman in Real life will not go back to the virtual life to speak with her.
