Are you looking for closure? Did the deterioration in your relationship with this provider leave you with. nagging feelings of rejection that you don't know how to process? What is going on now that causes you to consider reconnecting?

I don't think you can just call him up and shoot a big question at him. If you want to get any answers, I think you have to pay for some time with him. To just make a phone call would be unfair to him and even to yourself. While I agree with posts above that seem to say that life is about going forward and not rummaging around in the past, I can see where connecting with him might serve a purpose. But don't attempt to do this via a phone call. You can telephone him to make the appointment, but you would have to have this discussion in person.

Should you even be doing this? I don't know. I don't think it could do any real harm. It could be educational, if you handled it right. This T might decline to even meet with you. Are you prepared to feel rejected anew?
