After my paranoid night, I got stuff off my chest yesterday to a good friend and felt much better. My W then went out last night and when saying goodbye and kissing my son goodnight she lent forward to give me a kiss before realising and stopped herself. She then said, oops, I forgot, so I said you can give me a kiss if you like and she puckered up when closing the living room door on the way out.
Not reading to much into that, but it did give me a buzz like when you fancy someone as a teenager and get a little positive response when you think you've no chance.
Will try and look at more posts, and respond where I feel I can. it's a bit awkward as either at work or at home with W.
