From reading other posts about this kind of sitch, I think maybe you should actually help him pack, in a friendly way. You are ready to move on with your life, so you are not exactly helping him as much as helping yourself. In general I think this is go DB'ing too.
I've been getting a lot from reading Ready2Change's threads, and this was his approach. I don't know if I'll be up to it, but that's what I'm working towards.
Other than that, I don't think you should ask him if he is having second thoughts. Take care of yourself.
