"Not much"= constantly.
His tears are for himself and his frustration in continuously losing. Not for you or the damage being done to your relationship. If he could get away with it he'd give you no money at all so he could dedicate it all to his pursuit of winning.
Your feeling of going mad is how it's going to be but worse as it goes on.
I know how you feel. It's completely FUCKING STUPID but he is locked into the addiction and cannot, will not, see it rationally.
If he acknowledged he is addicted he'd have a tiny, tiny, chance.
As it stands he has zero hope of stopping and you have zero hope of normality.
If you really must stay with him protect all your assets and cash. Guard your bank account. Sign up to Experian and check your credit scores once a week
You must realise that he will, if he can, steal from you, pawn your belongings, remortgage your home, take out loans fraudulently in your name, credit cards ditto.
Addicts tend to be cunning, sly, clever and absolutely blind to what's right or fair.
I cannot warn you enough.
