Hi and welcome.
I feel your pain of the complications in your life.
I warn you you’re likley not going to go willingly on the path of for you’re sanity. Right now I suggest you go to Friends and Families in the forum page on this site.
Also as stated above Al- Anon in your area is a God send for what your going through. I lovingly call them the black belts on recovery, particularly for the family.
I wish you best of times on this new journey but if this path is chosen much sanity is restored.
I know what your doing and feeling is mothers instinct but it’s not doing him any favors.
BE WELL
