vtsister, I am sorry for what your family is going through. It is a tough situation. The court is sending him a message, please allow him adequate time to receive. Bailing him out will not fix anything. Just my personal opinion, but if you have money for booze, you have money to feed your kids. Instead of bailing him out I would use that money to help with the support of the kids. Again just my personal opinion.
I so hate this disease, it scars the whole family. Try not to internalize about his choices. The actions are his, as well as the consequences. I would have to put my energy into being a great Aunt to his children while he is unavailable. Take care.
