For the past 2 or 3 months, single colleague (Brian) and i (also single) have spent quite a bit of time together socialising outside work as friends but with some occasional flirting. I thought that something 'romantic' was developing between us, but thought it best to take things slow as we work together.
About 3 weeks ago Brian suddenly went cold, all suggestions to meet up were politely rebuffed and in work he was sometimes a normal colleague but at other times clearly avoided me. I knew that he had some stuff going on outside of work and thought that maybe he just needed some space.
Last night i found out that Brian has just started dating a new colleague who only joined the office a few weeks ago. I feel such an idiot, rejected, and also kind of angry with him for not fulfilling the idea I had created in my head. I not only feel like I've missed out on the chance of romance but also lost a friend. I've spent today trying to think of reasons why it wouldn't have worked anyway but that's not helping. Any other suggestions for how to cope with work tomorrow?
