OP, you can get through this, as long as your DH is 100% on board and is never allowed near a credit card again. You need to have total control over all spending and he should only have access to by essentials like petrol. It is not controlling, it is being in charge of the finances in order to stop it happening again.
I could have been you possibly, if my marriage hadn't ended as XH always had a problem with money and did actually go bankrupt for the second time a few years after we divorced.
I have seen debt problems in RL, and seen somebody help someone out by paying off their debts of £40K, only for them to rack up another £40K in 2-3 years and go bankrupt anyway, leaving the person who helped them stuck with a massive loan then in their own name.
You could ultimately lose the house, so you need to throw everything you can at clearing the debt, and do not build up any new debt either.
Check your own credit record
Check his to ensure that you have the full picture
Do not transfer any debt into your own name
Transfer debt onto 0% credit card if possible
Agree lump sum settlements wherever possible, or set repayments if they will freeze the interest
Do not give him access to credit cards ever again
Most importantly, never clear anyone's debt for them, as it doesn't teach them the lesson and they WILL do it all over again as they cannot help themselves. I have seen that happen repeatedly.
At least once somebody goes bankrupt they lose access to credit for several years. It stops them.
Good luck.
