Hi, I'm a recovering alcoholic and I feel your pain
I'm currently trying to get my wife back after "seeing the light"
What I'm going to say will hurt, and I'm sorry and I hope I'm wrong.
But if your husband HAS been sober for 18 months, and this is what he truely wants, I think you have to accept it?
I have only been sober 10 weeks, but in that short time, I now know what I truely want, I want my wife back. I wasn't really sure when I was drinking, everything was a haze and my moods changed with the wind, so I was very irrational at times, but I can now see and understand what I really want, maybe this is where he is?
But there is also reflection, he might now see the hurt and pain he has caused, and think that although you say it now, you may never forgive him for the pain he caused you?
I find from my experience,recovering alcoholics think about everything too much, and don't just live anymore?
My only other thought is if this change is new, is he drinking? Maybe he is drinking secretly and cannot let you see as he is embarrassed, he thinks it's beaten him, so he is running??
As I have said I'm only a short time sober, so these are just my thoughts to try and let you understand what maybe going on.
But unless he tells you truthfully, you will never know what is going on inside his mind.
Good luck
And I only wish my wife was as understanding as you have been.
