It wasn't long after I made my husband move out that I found SR. I watched him spiral down quickly and become someone I didn't even know. He knew I was working on me, seeing a therapist and going to Alanon. The more detached I became, the more he claimed to wanted recovery.
I was cautioned to sit back and wait. But I couldn't, I grabbed on to the first glimpse of hope I had prayed for.
I remember being told that his wanting to come home and reconcile so badly was cause for concern. I didn't understand! I kept asking why because I thought it was a good sign. It was explained to me that if he could gets things back to "normal" - he could protect his addiction even more by thinking "see, it's not that bad."
I caution you to sit back and watch. Hope is a great thing but can be watched from a distance too. Just sharing my experience, take what you want and leave the rest!
