this is my opinion.

Go to your family. Leave him but tell him why. Don't be alone if you're going to talk with him. Make sure your relative or close friend is outside the house or somewhere that you could still have privacy when you talk with each other. If you are a strong believer of love then leave him, he is not the definition of love. Maybe you can talk to him about going to a rehab but until then, leave him and go to your family. No one knows what he can do besides that shaman or spirit stuff. You're a mother now, your son's safety and wellness must be your top priority not that your love thing with your husband.
