I recently posted about the current difficulties between myself and uBPDh regarding the use of our joint bank account. Long story short, he's been unemployed for about a year, his unemployment pay ran out about a month ago, and I am currently funding our joint bank account, from which he's been paying all the household bills (mortgage, utilities) as well as all of our other expenses. My name is not on the house, he bought it before we were married and technically owns it with a friend who walked out on the investment a couple years ago. My name isn't on any bills either. While he's not making extravagant purchases, his almost daily spending of $50 here, $100 there for groceries we don't really need, hardware store items we don't really need, and his paying of up to $3,000 in bills at one time without letting me know has become a source of stress I'd rather not have. I do pay the credit card bills and car payments from this account, but I keep him in the loop of what I'm doing and when. I'm an accountant, it's my nature

But it's driving me nuts to try to schedule payments and purchases around what he does when what he does is never consistent and I never really know what's going on. Last week my paycheck was used to pay bills 10 days early before I even saw it. What's ultimately happening is that without any monetary contribution from H, we are spending more than I can support.
So I recently broached the idea to H that I would like to have my paycheck direct deposited into an account of my own, where I could attempt start some savings for us, and from there I would transfer money to the joint for bills and household. This was met with "I hate you's" and threats of divorce if I did such a thing.
Over the weekend we had a nasty fight. I had gone to visit my sister and her husband last week one evening after work (the night before he was in a mood and had actually told me I should leave and go to my sister's or a hotel for the night since he couldn't stand to be around me). He kept accusing me of going to my sister's to "air our dirty laundry" which was not the point of the visit but he got me to the point where I finally told him that no, I was no longer "sugar coating" things with anyone either. Implying that I am no longer lying to my family about his employment. Well he went off his rocker. He was divorcing me. I was a lying, back-stabbing b**ch and he hated me. He was supposed to take me to pick up my car from the oil change place that day; I ended up having to walk the two miles to get it. I was told if I took his truck he would report it stolen. When I returned home, our bed was moved into the spare room and he had an air mattress blown up for himself to use in our bedroom. (Huh?) AND he proceeds to tell me since he's divorcing me he's gone ahead and moved half our joint account into an old savings account of his that was never closed. Oh, and when was I getting the f out of his house.
I verified that he did indeed move half our money. "Ours" is a stretch of the word too. We're not talking a fortune here, but several thousand dollars. I slept on the couch for two days and did my best to ignore his trying to bait me into verbal attacks and even some really odd attempts (I think) to bait me into physical fights. Yesterday (Monday) I returned home from work to find him acting as if nothing had happened. His wedding ring was back on and the evening played out very civilly and he went to bed on his air mattress. He had, however, made a $90 grocery trip using not the money he'd taken for himself, but what was left in our account.
As of this morning he has not moved the money back. As much as I hate to do it I feel I need to protect myself if this is the game he's playing now. Today I plan to open my own account and move the remaining slightly less than half into it. I'm going to have to let him know to not use his debit card or it will overdraft the joint account. What I'm wondering is:
1. Is there anything legally wrong with what I'm doing?
2. Is this exactly what he's waiting for me to do so that he can say "AHA! You want to divorce me since you did this!"
3. How best to tell him if he wants to use his debit card he'll need to fund the account again or use the money he's already got?
And I guess most importantly:
4. Am I doing the boundary thing right? I was originally going to say something like "either transfer the money back or I will open my own account" but at this point (given that this is not something I want to tolerate playing games with) I'm thinking I need to just do what I have to do and say as little as possible and let actions speak for themselves.
Thanks all.
