Oh Stung, so many of your posts remind me of mine. My husband played the "recovery card" but he did it for me and us but not for him. It didn't last. I went through the same cycles of things being wonderful, then relapse. It simply blew my mind. How could he relapse after a fantastic, fun and romantic week away?? Eventually, his addiction took over and I just couldn't do it anymore.
Sadly, I finally ended things but I took the difficult road and continued to be involved with him. It was like pulling off the bandaid slowly. I wouldn't recommend that for anyone.
