Wonderful wisdom from experience on this thread!
I hope you are seeing Sweet that this is not at all unusual in recovery. We climb a ways out of the hole we've dug for ourselves over the years and then one slip leaves us plummeting. It is the nature of addiction and for us the addiction to the love we thought we were receiving from someone, the validation, the completeness and yet it always turns out the same, we end up realizing it's the same old bottom of the same old hole.
Please stay and keep working on you. This is why we seek support so we can break the cycle. Nothing changes if nothing changes. It just takes time, patience, and courage, and we are here to support you.
Get back to work on you. Cut off contact outside of business over the child and leave his recovery, or lack thereof, on him. If he truly wants it, he'll just go do it, he won't need you to endorse it.
Hugs,
Alice
