is it ok to ask, what outcome are you hoping for?
5 moves in how many years? you have to be exhausted.
what I hear in your post is his lack of participation / lack of responsibility is going to cost him$$$$$$$$.
But how does that help you?
Putting a dollar figure on his addiction, ( as in , any additional out of pocket expense) won't cure him or offer you security, or change this situation .
sending you strength, and hoping December comes soon for you.
