okay, since your assuming, I'm going to assume right along with you.
-what if he was trying to get a "feel" of how things are? -what if he was acting needy because he see's your life is going okay without him? -what if he really has started to see what he's missing? -what if the sky is orange and the water yellow?
As Bruce would say, Who cares???
Come on. Don't let yourself go there. Don't try to figure him out. You're doing so well, don't let this one phone call get to you. Please?
As for the resume, help him as you can and if he gets pissy, let him go on it.
You could always email and ask him in a playful kind of way that since you're helping him would he help you? Don't make it sound like you really need his help, but find a medium where if he wants to help you'd like it.
Okay, I'm stopping there. My brain and words are not connecting right now!
