Leaving husband for debt reasons

Would you leave your husband if he wouldn't stop spending? He gets quick loans, and things on finance and can't pay it back. Hes spent money that was for bills untill we got final notices. We've been through this before and I was happy to pay for a lot of things while he gets back on his feet financially but every time he says he's sorted another red letter comes through the door. he's still gambling ect. He's just bought a new expensive laptop. It's gotten to the point where I'm spending all my money on my husband and am struggling to put away savings for our kids...

It's been like this for years so he's not going to change but it also doesn't feel fair to the kids to break up due to money.
