you seem to be doing quite well. my W is about same age as yours. I think there is also an element of experiencing her 20's that she missed out on. But as my mum et al have pointed out - in their generation it was the norm to marry 19-21 and kids soon after. So NO excuse really.
i dont think you can afford to be 2nd guessing yourself re: the pulling back on communication issue. Its hard to know if she will interpret as such, and really you should be able to point out that "hey - you created this sitch", but WWs are not subject to reason or remembering anything that doesn't please them.
