I'm recently divorced and I've worked with my male colleague for 5 years. We have always go on well but nothing more. We do share the same sense of humour. At a recent meeting we were sitting close together and our legs were touching. Usually one of us would say sorry and move our leg away, but we ending up with our legs touching (knee and side of calf)for most of the 45 min meeting, neither of us moving away.
He is quite attractive, though I've never considered him in that way, do you think I should read anything in to this?
