With our Addicted Daughters (AD) and Addicted Husbands (AH) and other addicted folk, I've discovered that I will never. Ever. Nope, not ever, ever, ever receive "permission" to set a boundary. But I was always asking and threatening and trying to get agreement from the addict. Looking back, I feel kinda silly. But today, they never even know that I've changed my email or taken the phone off the hook, or don't respond to texts. Because I don't tell them. So they find someone else to pick on, lean on, live off of and use.
I wish you the best.
