You can’t help him, he is responsible for getting help. The more you try the less he will want to. By all means get some info on where to get help and help him that way but your just going to wear yourself out trying to make him.
You can lead a horse to water and all that.
14 years in the same boat as you has taught me a lot. Nothing is ever enough, there’s always a reason or excuse why they cant/won’t get help, it’s mainly someone else’s fault and they will lie, beg and steal to get their next hit. You will never know the true extent of their addiction.
Stop battling him and start focussing on you and your kids. Distract yourself with them. They need you, he doesn’t. He’s an adult.
My husband has chosen crack and heroin over family, managed to miss out on 3 kids growing up and has wasted money and time on drugs. I havent allowed myself to waste time on trying to change him. And I’m glad. I hope you get the strength you need to concentrate 100% on your kids and not on him. Look after yourself. Be kind to yourself. X
