Britt, please don't take this the wrong way because I mean it with all the care in the world, but:
SHUT UP, WAIT AND THINK!!!
Nothing's changed in your situation. The only thing that has changed is your own perception of reality. So I'm telling you again: STICK TO YOUR PLAN (the one Gucci outlined for you)
Calm down, ignore his existence. Take your kids and get out of the house. Go and do something. Don't be there when he wakes up. Return after you know he's left.

Gno is right. No matter how much you may have thought you have geared yourself in preparation, you are in pain and shock. Not a good base to have any discussion.
Just collect yourself, and let 1-2 days pass as you come to terms with your feelings. Get as much evidence as you can.
Much easier said than done of course. Sometimes I think back to my sitch and the milestones and all the things I did wrong (and there are many). Not reacting upon discovery is probably one thing I'm pretty sure I'd still fail to do properly even with hindsight.
