Glad you got the book deal, something to do during the day. I understand the need to fill the hours, I'm around all day and that would be when I'd want to email or call him, but hold off.
And, I wouldn't call him on V-day. You are doing great, why break the streak? Your PMA seems up and you are doing it on your own. Keep dropping that rope, give him time and space and keep working on you. How would a phone call to him get your closer to your goals? He isn't going to listen to reason, he doesn't want to feel pursued and if he is nasty to you, there goes the PMA. I don't see any positive in calling. What do you hope to get out of a phone call?
