BRNR, It is very normal to feel/react the way that you are, especially when you hear that he's filed for divorce. It makes you rethink/revisit what's transpired and even though you don't think you want him back, you were possibly still holding out a little hope that things would change.
He's acting strange because he knows he's filed and he didn't even let you know. It's called being sneaky and underhanded and he doesn't know how you will react to the news. They get weird when they do something that will have some fall out.
I think you need to sit quietly and the answers will come. He's not going to be able to contain himself for very long and will have to find out what you now about the divorce.
I'm very sorry that he's rocked your world a little bit.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
