Update: I still could not manage the kiss last night, and things were a little out of sorts anyway as I came home to find out my oldest was having a sleep over. I need to remember school is out and sleepovers can happen in the middle of the week...
Anyway, when we finally did get to bed, I thought I would try a little non sexual snuggling. Out of the blue, the wife goes "should have started that a little sooner. It's a little too late now". Instead of getting upset, (I wasn't trying anything, it WAS too late, but those words just piss me off now) I just took her at her word and did not get upset. This morning, I decided to try something different. After I got out of the shower (I am a very early riser, 2+ hours before the rest of the house) I decided to see if I could initiate a "joyful wakeup". At first the wife started talking about how she didn't sleep well the night before, which has always been a very common excuse. Again, I decided not to get upset and just suggested we snuggle for a few minutes as I was ahead of schedule. After a couple of minutes, she suggested we let one thing lead to another and it did!
