A suggestion? Print out that last post and make multiple copies and tape them up around your house.
Be very, very careful, sweetie. What you heard was an hour’s worth of self-pity, lies, and rationalization. What he heard was you listening to his poor-me crap nonstop for an hour and then validating it by sympathizing. That’s something narcissists (whether intrinsic or addiction-caused) just love. He’s going to try to come back for more. I would bet an appendage on it. He’s already texted you afterwards. And he’s whining about having no money...that’s a red flag right there. And I’d bet another appendage he hasn’t been clean all the time he’s claiming, not that it really matters for you. Just don’t get sucked into to praising him for what is probably another lie.
Be very, very careful. (Did I say that enough?)
