thanks all; I am feeling good about the decision, so I think it must be the right one. somewhat concerned about keeping up social connections, but that really wasn't much helped by school anyway, so I am hopeful.
Grinity -- yes, I am definitely considering at least a couple weeks of 'unschooling' to help ds get back to himself.
Just batting around ideas with hims for art and language arts he was very excited so, again, things are looking ok.

2gg - DH mentioned there is a 'partial enrollment' option that seems to be available, but the only course dh mentioned keeping would be chorus, and it's just not worth it. And I can only imagine that he wouldn't qualify for one reason or another.

Now mainly wondering whether to put this through 'asap', or wait til end of semester/christmas.
Any thoughts on taking this slow at this point?
