How do I expose the affair

[mb28]

Seen H last night and I think I did very well. When he came to get kids, he told me that the divorce paper work is done, but he didn't file them. He said his L said he can wait as long as he wants. He asked me if I wanted to see them, and I said no. I didn't get emotional, and yes he tried to bait me. Here is a summary of the convo:

H: I don't want a D, I just don't know if it will work between us
M: Sorry you feel that way
H: I feel like you just want me back so you can hurt me again to get revenge
M: Sorry, but that is not true
H: I just want my old life back, when we were happy
M: I believe we can have that again
H: I know you and you hold crudges, and will resent me forever, that is why it won't work between us.
M: I'm sorry you feel that way. Through this ordeal, I have realized what is important to me, and that is my family which includes you.
H: I just don't know what to do, I'm so confused and lost
M: I better go, I don't want to be late, see ya!!!

I did this all without crying, which I think confused him even more. Please advice, on if I said the right things. For once I finally just listened. There was a lot more said by him, but not much more from me. He was really trying to open up to me I think.
