I can imagine that you would be going through an emotional roller-coaster since receiving the reply! I agree that he probably didn't even think of the sentimental touch of a handwritten response - I am sure it's an emotional time for him too, maybe typing a response gave him a little more confidence?

I would suggest you sit down and think about all the questions you want to know, once they are all out on paper then maybe you can sort out in your head what you want to know first. I guess if you are worried that the contact will not continue then asking the tough questions first is the way to go - but hopefully it won't scare him off!

Good luck with it - and keep us posted because I would love to know what happens!!
