I'm glad you had a conversation w/him and yes, I do think you satisfied his "need" to hear from you. He's definitely feeling a bit uncomfortable about meeting you face to face and wants to do a temperature check prior to meeting up. If he had sensed that you were angry, the meeting would not take place.
I do hope that you will be able to get some of the work wrapped up before the end of the year. I might be wrong and completely off base, but if he has some type of communication w/you, the drama may dwindle a bit over the next couple of months. He has abandonment issues and it will be interesting to see what happens when the divorce is final.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
