No need to wrap up, my friend. There’s lots of support here, 24/7, from people who understand. Your husband’s drug if choice doesn’t matter so much.
I’m sorry you have been so deceived and disrespected by someone who is supposed to be a better partner to you. Sounds like he has swapped one addiction for another. If you feel you need to have this confrontation, okay, but keep your expectations in check around his response. And keep taking care of yourself. We’ll be here.
