I've worked with a guy for the last month, we email a lot and flirt. Both free and single etc.
Even though we work together he lives in a different city to me, and he happened to be going out with his work team in my city and then I asked him if he would like to come over to mine afterwards as I knew he wouldn't be out long.
(We've been trying to arrange a date for ages, but working different shifts, different hours and living in different cities made it difficult)
He came over, we chatted, laughed and kissed. He left at 1am.
As he was leaving I said - text me when you get home.
I haven't heard from him since.
