I have a lovely colleague at work. We are both single. I really like him, and I think he might like me too. We've started seeing a bit of each other outside work, usually with other people around. Lots of smiling and eye contact, and a bit of texting.
IF I am right, and he is keen on me, can I just sit back and let things develop? Or is there a danger that neither of us will make a move, and it will all fizzle out?
