Praying-you hit the nail on the head. If you remember you and the kids are just there to serve a fix, then you'll be just fine. My ex reached out many times with drunk messages over the last year-most likely when he was done with another flavor of the week. It is what it is/and these guys can't do anything on a consistent basis. Period. Just let him be, but stick firm to your boundaries and don't engage with crazy. He's full of hot air.
