Good for you. I think from time to time you need a break - you need to examine your intentions - modify behaviours that are not getting you intended results, etc.
Regarding the rut - I hear you bro! When we were on our family vacation this summer (about three months after I moved home) we had a great time - got really close and I thought we were on the right path. As fall rolled around, we bought our new house and the stress of the holidays approached - I sensed a rut.
So I too, took a break from the board, hunkered down my DR/DB efforts, re-established goals, and GAL'd. It took a couple of weeks, but slowly the W and I started really falling back in love. This culminated with an admission by HER of me being "her true love", at dinner with MY family. This was a huge breakthrough.
What I noticed in the rut was exactly what you are noticing - as we piece, we start to "expect" things which might lead to disappointment - which shows on our face and in our moods. I know I jettisoned that (though it took a 2x4 to the head back in say November) and instead reminded myself to give love unconditionally and lose the expectations. A tough feat, but I think worth the effort. I think our S's can sense the feeling of let down and can become bitter. In their mind, they are giving all they can but it never seems enough. I know this was a root issue with my W way back when.
Time and patience and focus on yourself - the W will notice. Move back to what you were doing pre-reconciliation and stay there. At the same time, take time to really listen and understand her - I know as busy as we are, I almost have to force myself to slow down, listen and understand - NOT FIX - but understand. If you haven't read "For Men Only" by Feldhahn, please do - some great stuff in there, and it can be read in about a night.
Good luck GH - take the time for yourself. You'll be fine.
Happy New Year.
