Jailhouse remorse is more often the case than not.
I clearly remember the year my EXAH went back to prison on a parole violation. We wrote each other every day. He was my soul mate, and told me everything I wanted to hear. I was the faithful wife who stood in line on visitation days, waiting to walk through the metal detector and vowing I'd endure whatever I had to in order to "support" him.
Ugh.
The truth of the matter was his jailhouse remorse lasted less than a month after he was released, and he was back to the same old same old, only worse.
I hung in there another year because you see, I was sicker than he was.
One of the greatest gifts I gave myself in recovery was leaving him and never looking back.
