Believe nothing that he says and only 1/2 of what he does. Try not to mind read and just focus on improving yourself. You thought the last call was not going to be good, but looks like you did a GREAT job. Keep a PMA, validate and don't let him bait you into an argument and you will do great, AGAIN. You got this! Just let him speak his mind and keep your answers short and sweet. Be mysterious. These calls are a good opportunity to gain insight into his issues in the M and get a better understanding of why he wants a D.
Not sure what the sitch was why you got off of social media, but I think it would be a good choice to get back onto FB or Insta. Can you elaborate on what caused you to get off FB? Was a sitch with your H a factor? You don't have to connect with him, but I am guessing that you have mutual friends and that should do the trick. I think that would be a good way to show off your GAL'ing and "As if" attitude and a good reminder of what an awesome W he is going to lose.
I'm not a vet by any means, but here to support. Don't give up, you're just getting started and going great.
