I'm sorry for what brings you here but glad you have found this forum. This is not a recovery plan so of course you can't trust it. The man is free to do what he will, but you are also free to live your life without the drama and misery. Unless you accept his as he is right here and right now and can live with him as he is right now, you may want to consider breaking things off. His alcohol use is his business and should never have to be yours. I wish you well.
