Are you busting your divorce or looking for a shoulder to lean on during this separation and possible eventual divorce process?

Ask him the question,
"I noticed you took $125 out of the billing account and I had some bills that were being paid and had to make some adjustments, I think we both know that this account is used for paying the bills, I would appreciate it if you would repay this money as soon as you can, more importantly are you ok?"

You don't have to kiss his a$$ or anything but you can be human, even if he isn't, there is nothing to be gained by stooping down to his level (or anyone else's for that matter) when a relationship goes sour.
