Should I close the following bank account?

[hnhlvr]

My husband and I recently opened a new joint account at a different bank for obvious reasons, but then I wrote *him* a balance transfer check and he took it to this new bank and cashed it there. He would have written our account number on the back of the check. Is that reason enough to close it since the account is in both are names?

He's firmly against closing that account, but I'm so paranoid at this point that I've been wanting to do so. . .

Thoughts?

Our ccs are in default.
