Lots of great advice here, radishes. I agree the issue seems to be with you. If you try a paradigm shift, a shift in perspective, it's easier to see. Imagine if you were ready to quit and he wasn't and he was pressuring you to keep drinking because he wanted to. Then imagine he woke up one day and was ready, and you could then start working on being sober with mutual support to each other. You would feel happy and excited, instead of depressed and resentful.
In reality, the pretend situation I've described is externally no different from where you find yourself now, the only difference is you and your feelings.
It's easy to say I know and harder to do. But the point is that it's all about letting go of that resentment about what happened in the past. Put yourself in the imaginary scenario and see how you would feel and what plans you would make and it might help you move forward.
