Jayner, I am sorry that his addiction has caused you pain, it's a pain we all understand too well.
He may or may not be clean, but his addiction behaviour is still there, and you are so wise to see that and move on. You handled Little Miss New Gal with grace. Your side of the street is clean.
They both sound like they are still caught up in the drama and again, I see your recovery shining when you refuse to be part of it.
That said, I know your pain is valid, but one day soon it will begin to heal and you can move on to a better, healthier life, leaving all this drama in your dust.
Hugs
