At the end of the day, how you feel about your H's actions is very likely how my W feels about my actions. As though I've abandoned the kids, become a part time dad, only being with them when it's convenient for me. Which, from where I stand, is as far from my truth as could be.
So I understand how frustrated you are with your H's actions. What I do know is, my W probably has expectations of me in regards to my relationship to our kids. And what I also know is, I'm doing the best I can, no matter how it might appear, to my W.
