Hon,
What are you afraid of.....He will get drunk, he will be with another women, he will kill someone drunk driving, he will wind up in jail or the hospital?
These things are all out of your control, you are not God. What he does has nothing to do with you. We all love our addicts, but we have no control over them. We should pray for them and love them from a distance.
Work on a plan... he will reach out, probably apologize if you talk to him. If you don't talk to him then he will leave you mean drunk voice mails. Then he might stop over to your house and be kind, then mean, then kind. He is all over the place. Have a plan, can you go to a friend or neighbors for a few days?
How can you avoid him, as they say on SR no new contact means no new hurts.
