I am getting ready to file- keep or close joint checking account?

I am afraid of two things with my soon-to-be ex-husband . We are basically living paycheck to paycheck and we both work and make about the same amount of money . My concern is once I file he will start more aggressively pain down his credit card debt and or refuse to pay the mortgage on time or paid it all . Every month we deposit our paychecks into a joint account which barely not even covers the cost of our mortgage taxes utilities insurance food etc. . Unfortunately my husband is taking out a few loans without telling me as well as one of his credit card debt so every month for hundred here for hundred there another 400 of debt that he is taking on is hitting our account . My fear is if I close the joint account he will not be compelled to share his own account help pay for the expenses as I know he's going to be a very difficult person to divorce .but my fear is if we keep it open and I keep depositing my check he keeps paying down aggressively his credit card debt and loan
