I agree with John - take it slow and dont make any quick decisions. Sara has a point about him getting tougher to deal with after the guilt subsides, but I am not so certain his guilt is going away any time soon. I filed back at the first week in January and my W's guilt is much worse that it was back then.
And once you have a plan, you are probably going to have to be the one driving it along. Dan is too wishy washy confused.
