I’m so sorry Pocahontas—-this is heartbreaking 💔 for you.
I agree completely with everyone else’s advice that you need to RUN away from him. Fast!
Go no contact immediately.
Not only does he have the addiction problems but he sounds like a narcissist, in the very least.
The back and forth, love-bombing then ignoring you, the additional girls on his social media all add up to a very bad ending for you and your daughter.
Just be prepared for lots more attention once he realizes you are gone. Ignore him, ignore him, ignore him!
