I definitely understand the sanity part and being "no other choice." At one point (for my sanity) I had plans to move to the other side of the country and leave the kids with H (that was a threat I used to use because I knew he would be overwhelmed as a single parent!) and I imagined myself on a Florida beach, tropical drink in hand, a stack of great books, and hottie guys walking by..... still sounds kinda good!
There is no arriving, ever. It is all a continual becoming.
