I think that sometimes those of us who live with spouses/partners with addictions miss a very important point.
We begin to believe that their addiction - recovery, relapse, commitment, failure - is the key around which we base our decision to stay in the relationship or leave.
It is not. The key is whether we have a loving, committed, sharing partnership with a lover and friend that we want to sustain for the long haul. Alcoholism or other addictions are clearly major reasons why some of us can't sustain our relationships, but they aren't the only causes.
But we forget that marriages fail for many reasons, and if we just don't like the person, don't want to be in such close commitment anymore, whatever the reason, we don't have to. Whether or not they fix their addiction.
We kind of box ourselves into saying "Well, if only s/he took care of their addiction, it would probably work, and I owe it to both of us to stick it out". Well, we don't OWE it to anyone. We can choose to stay, and we can choose to leave for reasons other than their addiction.
