Mixing your business with pleasure is not a wise move right now, so if you are thinking of cooking up a romance in the workplace, turn off the heat ASAP! Get back to work, and stop spending so much time at their desk. Things are all coming together on a big project, and it looks like you are going to hit a home run, perhaps even a grand slam. Invest your energy is something that will definitely help you, not on someone who might distract you from important things.
