I hope you really 'heard' him (((((B66))))).
Bluntly, he said .......................... you are out of life preservers, he is an adult, not a 6 year old, and it is time for you to take care of you and your child(ren) not him.
You are not responsible and it will not be your fault, if he 1)goes back to drinking, 2) attempts suicide, 3) ends up in jail for whatever reason, etc etc
Remember, we are with you in spirit. In whatever room you are in at the moment, just picture it full of SR folks!!! Believe it or not, that does help.
Love and hugs,
