Bear with me please before you all immediately say YABU. I've been working very closely with my manager for a year now and we get on extremely well, lots of similar interests, same sense of humour etc, I massively fancy him. I've never acted anything other than professional because he's my manager and also because he had a girlfriend. He's made some comments to me recently which imply that him and his girlfriend are no longer together and I am single.
We both move onto other projects in a few weeks and are highly unlikely to be working together again. When we're finished, I'm thinking that I could casually suggest to him that we go for a drink at some point to stay in touch. I would obviously be hoping this could lead somewhere but it may not. Would it be a very bad idea for me to do this?
