<human>: Give me the gist of the text in a nutshell

One of my best girl friends just got out of a long relationship and you feel better she has been spending a lot of time with me.

We have been friends for about 6 months and the relationship with her ex has been about a year. Even in the shirt amount of time we have become become extremely close and I treat as if she was a girlfriend.

The problem lies however in the fact that I'm not sure if I am catching feelings for her or if I just really want to have sex with her thus putting up a façade for myself. Looking into her eyes and looking at her chest produces the same result for me and I'm not sure how I should go about solving this problem. 
Thanks in Advance for your help.
