When something isn't working, you need to try something else. You've tried the waiting game and then end up calling him, so do something different....he knows you very, very well and he also knows that eventually your anxiety takes over and you call him...so prove him wrong. Don't call him at all and see how long it will take him to contact you again. I know you feel like you need to stay in touch w/him, but I can assure you, it's not that he doesn't want to speak to you...but his focus is on himself and doing whatever he needs to do ease the ache within himself. If he didn't want anything to do w/you, he wouldn't be contacting you about your daughter's info, etc.
You have to try to look at him as a former school friend, i.e., someone you don't hear from or see but once or twice a year.
It's time for you, Coly, to live your life and when he senses that you've moved forward and are having a great time, that is when he'll get curious and want to contact you again.
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.
