what's to decide now? Legally nothing, right? I mean signing stuff only makes it more complicated if something happens to him.
So all you are really doing is gathering intel (papers), correct?
I'd back off the flowers for now (I get why and all, but it'll look over the top if it happens again too soon. but keep going out and smiling at the good times you are having. Be mysterious and volunteer as little & vaguely as possible)
And keep on your program. Remember, he has to ponder at least the possibility of OMs in your life (and your kid's lives) before he starts to wonder if he's losing something important.
His tantrum might even be a good sign though it's a drag. Something bugged him.
Next time you want to validate him, be sure to also set boundaries. If he goes off on you for something or lectures, you can tell him how it makes you feel.
OR
if you think he sounds like the old you, maybe suggest he not repeat your mistakes
b/c you learned the hard way that words do hurt. Just a thought.
Carry on!
