Well, sounds to me like he may still be somewhat conflicted...
I would listen and validate primarily. Be as strong and serene as you can manage. have a look at the validation cheat sheet.
If he is asking you to make decisions, buy yourself time....I'll have to think about that etc..
But if there are clear boundaries, you can state them. Mine was that I won't be in a M/R with H when he is involved with OW. We don't do family stuff and I'm not his friend.
Above all, remember it is early days. Things are pretty unstable in your sitch...as in mine - and everything can change.
And remember, you are not a victim here...you are a lovely, self-respecting woman who is deciding what she wants to do with the rest of her life....with or without H in it!
Good luck x
