My Husband Has A Gambling Problem. I Live With Him But He Usually Gambles All His Money I Don't Know If I Can Get Him To Pay Child Support ?
I think anyone who has had any contact with this illness would give you the same advice: Leave, take the children and don't even consider going back until he has undergone treatment. You will be bankrupt anyway if you stay with him, so however financially difficult it may be to leave, from what you say it can't be worse than staying.
You can find some advice at this forum where someone discusses a problem similar to yours, and several links are provided to organizations where you can get help. As for child support - of course the law would require it, and maybe the shock of getting into trouble over child support would help him to address his behaviour.
While maintaining confidence in the future for myself and my family, I increasingly forgot that I sometimes needed a break myself. As a result, I couldn't work, I had to stay at home. That's when I tried the site https://duckdice.io/dice/dai-dai from an online casino and raised a steep amount there. I sent this money to charity, I don't need it.
