I tend to agree with what FreeOwl said, it all starts with quitting the boozing. I know it sounds tired and cliche, but its true. The saying is "there is nothing alcohol won't make worse"....and I believe it to be true. You need a clear and free mind to start to unravel the current situation. The trust issue is huge, and its not going to come back while your actively drinking. And even when you quit it may take a long time. Be prepared for that. Wish you the best.
