It's hard to reconcile the behavior of our WAH's (who doesn't help out the mother of their kids when she is injured?!) during this time. My H has his moments of cooky-ness but I frequently want to karate chop your husband's skull. Not that know anything about karate nor am I a typically violent person but these WAH's know how to stir something deep in us and putting myself in your shoes, I'm not sure I would have held on like you have...
However...
I must say that your tone and voice seem very strong and steady. Your advice to Maybell on her thread is so telling of where you are in your mindset while also dealing with the flat out B.S. of your husband's walk-away-ness and abandonment.
I am confounded by the prospect that being willing to do better and knowing HOW to go about it isn't enough for them to say, "hmmm, let's give it ONE more try".
