I need advice-should I leave my husband?

I’ve been with my husband for 12 years total. He has always been bad with money. He is a big spender and doesn’t comprehend how to save anything.

Years ago I found credit cards that he never paid that severely affected his credit. I paid off all of his credit cards and corrected his credit.

Now we are in the process of selling our house and trying to buy a new house.

I just found a secret credit card that he had that is three months past due it has never been paid. I found the credit card statement in his truck. I strongly believe he was trying to hide this from me. It was only for one small $70 purchase but now it is up to $200.

I am so upset with him that I feel like ending our marriage. I don’t know how I can have a stable future with somebody who doesn’t care about planning or saving money.

He constantly spends and spends. We have tried to come up with a system to have him stop spending as much but it never works. He will try for a couple weeks and goes right back to his same behavior. I really think I need to move in with my parents get a job split custody with him and move on with my life. Has anyone else ever had a similar situation?
