Seems like now the problem is your husband. A,B,C, who knows if there will be D, E, F, G..........
If he is not serious is changing his habits, hand him over to the police! They can help him change and solve your problems with the loansharks too.
How long are you intending to help him in repaying his debts? You have 2 kids to support already. And he as a man cant even bear the shits he have created? Shame!
And with his thinking, i believed that he might be thinking, " Oh, I've got someone to pay off for me, who cares, Just gamble more!"
Loansharks interests alone can suffocate you already. And with monthly installments that you offered them, you're just paying off part of the interest alone only.
I dont believe that the loansharks will spray paint at you when you go out. Just avoid going out at evening/night. Thats when they start "working".
