Your last post struck a nerve in me. I too have wished many times for a loved one to recognize effort AND reciprocate with some of their own. I think for all the talk though, some people are just not wired to have that mindfulness about their relationships. Either you have to literally tell them what you want before you do things from them - or throw the dice and expect them to aware of what's going on (bad idea usually). I had a lot of resentment about this because things were rather one-sided on the scoresheet after a while, but finally recognized what I literally had to speak up and say. And I hate doing that really, but it's a solution that seems to work.
Best of luck with your partner - and good grief that baby needs a normal sleep schedule!
