DB, How did he tell you? Was it a phone coversation or email?
You haven't replied have you?

You are right to be cautious. But I think this is an important opportunity. My feeling is you can't go running back into his arms.. not straight away. You need to keep your composure.

I feel out of my depth...

My suggesting is to post a new thread in Newcomers to get some attention (I know it didn't work last time!!!).

make sure you put a link to your old thread in it.

How does that sound?
