Help!

I got two text messages from H today (he is at a work convention with OW). These came after our phone blow-up from Sunday...

text 1:
"I'm struggling with how to proceed. I'm not trying to hurt you. That's not my goal. I am trying to separate myself in as painless a way as possible. I don't know what that is, and I'm sorry I haven't always made the right choices in the process."

I responded:
"I am sorry, you are so vague that I honestly do not understand what you are trying to tell me." Are you trying to apologize, justify your actions or what? And what "choices" are you talking about."

Text #2:
"I wanted to talk about how we move forward. It's a painful situation and my attempts to neither hurt you nor be hurt by you seem pointless now. I've failed to do either. I want the least amount of pain possible. You don't want to be divorced and I do. I want to talk about that."


So he's basically asking for the D BY TEXT while he is with OW...

My question now is HOW SHOULD I RESPOND? SHOULD I BE COOPERATIVE THRUOUT???

What is the best approach, since it looks inevitable now. Please help me. I am devastated. I have been dreading this moment for almost a year. All my efforts (and mostly failures to DB) have been in vain and I really blew my chances. I had 10 months to convince him and I didn't...

What do I do???
