text: I have been in the same situation and personally I would not advise you to go ahead.  Its best to just stay friends. I fell in love with a guy who was my colleague, my senior and I really thought he was the one and now he has dumped me after we had decided to start a family and get married.  Now I'm left holding a baby and having to worry about finding another job.  It's just not worth it because when things do go sour it will be really awkward not for just you but for everybody else that you are working with.  Try and find someone outside the office it would make your life a lot less complicated.  At the end of the day its your decision, I really hope you make the right one!
