New here but learning slowly. Advice appreciated

[Albuquerque]

So just got an email from H about going forward with "legal separation". I'm not sure whether he means "legal separation" or D since he hasn't ever once uttered the D word. But since he talks about not wanting to fight over stuff, that sounds more like D to me. He tells me that legalzoom has a packet and stuff. Not sure quite how to respond to that. I will not be moving one step forward on that front and will leave it to him.
He also mentioned again the need to formalize the finances. I agree with him there. He's kind of been transferring what he can over to our joint account and I do agree that should be formalized. I'll be going through finances and figuring out what should work on that front.
But the separation thing is admittedly upsetting although not surprising. He's been cordial and friendly but firm minded about not looking back. Maybe this is what he was ACTUALLY wanting to talk about on the phone and then chickened out or something. Frankly I'm a little surprised by my emotions. My heart did a flip when I read it and crying crossed my mind, but I haven't. I know this is not about me or my failures. It just saddens me for my daughter's sake. I suppose in response, I'll just say, "do what you need to do". How does that sound?
