Cheers to you. I admire that you keep doing right by your kids no matter what your W dishes out. I've read all of your threads and have not noticed a single instance in which you involved your kids in your problems with your W. Indeed, you have done everything possible to compensate for their mom's dysfunction.
It's a fine line you are walking between enabling your wife's poor choices and looking out for your kids best interests because those interests often depend of her choices. I think it is good to err to the side of your kids, even if it shields your wife from some consequences. I know it's tough because you are the one that has to deal with the pain and frustration, yet you keep doing it for their sakes. You are a class act.
BTW--My oldest boy broke his femur at 18 months old. He was in a body cast for 4 weeks. So Red really should knock on wood.
