Maybe your reaction feels bad on the emotions side, but I think your response sounds fine. Deep breaths! It sounds like he has figured out exactly where your button is - talk of your daughter - and he's pushing it all he can. I wonder if you can try to make it a habit to say to yourself, "Step away!" when you hear him bring up your daughter in any way. You are not legally obligated to discuss this with him right now, or to sign anything right now. I'm a lawyer, and I'd say not to sign anything until have spoken with your attorney and seen what options you actually have!
