My EXAH went through treatment (30 day inpatient), and so did I (30 day inpatient). He chose not to embrace recovery. I did.
I strongly encourage you to dig into your own recovery, through a 12 step group like Alanon, perhaps some individual counseling.
Stay in today. Expectations are resentments waiting to happen.
For me, recovery was an extremely slow and painful process. I retained many of my worst traits even after treatment, which eventually led to me relapsing after 4 years clean/sober, and then finally hitting a bottom in my codependency 9 years into being clean/sober again.
I will never be the same person that I was before alcohol/drugs, nor would I want to be.
I was miserable inside. Alcohol/drugs were my solution for many years. Take away the alcohol/drugs, and that's where it gets really tough in recovery. I had to literally learn how to cope with life on life's terms, something I had never done before.
Take care of yourself and your well-being first and foremost. :ghug3
