My husband was like that and he destroyed my account by letting his friends have access to his debit card, very long pathetic story.
It's taken a long time to be able to trust him with money after that, but now his mother is on an account with him, and she recieves statements, and the three of us go over the budget each month, instead of just leaving him alone with an open bank account. We are trying to move into a house, and for the most of last year he has been a lot more responsible with money.
There have been a few incidents of "splurging" but it's no where near as bad as it used to be.
I think as long as we're all on the same page so to speak, with whats going on, and he's honest about what he's spending, it makes it a lot easier. One time he spent $600 on a computer he wanted, and I had no choice but to call his mother and tell her so she can record it on the budget plan and he was all stressed out and thought we would make him take it back, and it turned out we just wanted him to be honest so we don't wonder where the heck $600 disappeared to.... And he has to be able to trust us, too... Which is hard for him,,, but like I say, so far it's working.
And the scary thing is he got a new pay pal card, and all he has to do is go online and transfer however much he wants and i'd never know it.
Except the statement comes in the mail, and he's busted. So his mother made him promise no more buying online. ;)
he only does these things when he's going through depression again, my main clue is when he's craving chocolate, and all he wants to do is veg... Next thing I know we're 200 dollars short for the month.
Now i'm not sure about the medication, you mentioned depakote....And something else, my hubby is taking lithium and for the most part it just sorta takes the edge off I guess, keeps him balanced until it's time for his next dose.
His doctor said, and its in the handouts from therapy, that spending money, or "splurging" is part of the depression, it acts sort of like a "high," it's usually temporary but they (someone with bi-polar) can't control it.
Thank god his mother and I are pretty close, we can handle this together and we always help each other de-stress, and we usually have a cup of tea together, and come up with new ways of handling ways of telling him no. Sometimes it sucks but we have to be strong together.
~good luck to you.
