what hell do I do

Have you eve had those people that you cared about show up in your life that there is something there that intrigues you about them something that pulls you in and doesn't let you go about them well I am sort of in that dilemia I started working with this one guy and ya know I thought he was such a dog his tail wagged for anything that walked But I took a chance and let down a few guards not many but I got to know him and developed a friendship with him and started to really like him alot well nothing ever happened at all in between us but we became good friends somethings happened and we ended up going our seperate ways and kind of lost contact with each other then it happened the other day at work who shows up he does and now we are going to be working together again one of my close friends at work talked to him and found out that he feels about me the same way I feel but me and my cynical ways thinks that I would be just another notch on his bed post People say that he does feel the same way about me but I dont know what to do so WHAT THE HELL DO I DO?
