Hi Tipper, It sounds like you had a great 4 days together. You did something different (you spoke your mind about how his actions were bothering you) and the result was a good one!
I know exaclty how you feel about starting counseling because of his addiction. I went through the same kinds of thoughts- because of his addiction, I had to go through x, y, and z. But that's how it is- you either choose to be with the person with the addiction and deal with it in a healthy way (i.e. by seeking counseling or support in other ways) or move on and decide that you can't deal with the addiction. Hopefully, while you're taking care of yourself, he will realize that he needs to take care of himself also.
