Real quick answer?
No.
What you can do? Make choices about what you want in your life regardless of the fear of losing someone who will not respect those wishes, or boundaries.
When you decide to live more for yourself, and not allow your day, night, week, or, for many of us, decades to be dictated by whether your alcoholic significant other is able to be a respectful person to you, or even to himself...Then you send a very important message to him.
It is not your job to make sure he gets the message.
He may not get the message..., or he may see the message and still roll over and stay passed out on the couch. He may wake up 5 or ten years later and wonder where you went.
Those are 5 or 10 years of your life that pass by as well.
Start thinking about whether you are living the life you want.
Write down what you dont want to live with in a significant other anymore.
Keep posting and reading here. It is invaluable.
