Wow, ok. Damage, but nothing that's going to break the bank either way.
I would reply "Yeah, well this is pretty difficult on all of us."
or
"Looks like we both have some decisions to make. Not sure what the future will bring but I've decided that I'm at least going to be honest with myself and with you moving forward, and calling it what it is."
or
"Yeah I've gotten pretty good at 'blown away' too lately. Lots to think about."
Just some suggestions. You could always just ignore, as there's really no question in there and it's not about the kids.
