Congratulations! Woot, woot!
I gave my alcoholic husband chance after chance after chance. After rehabs. After periods of sobriety. After all things done, I trust it was my path for a reason and I have no regrets. I am now in No Contact.
I recall being in the therapists office at the first rehab and feeling very much like you, that it was not in my best interest for everything to return to a normal atmosphere. In ignoring that gut instinct and looking back on this, it validates trusting my gut instincts!!
