I am sorry your turned to A talk. We have had a lot of those. It is discouraging.
But on the other hand it does show that he is trying to figure it out in his head instead of just sweeping it away. That is encouraging. He is also trying to involve you in the process. That is a sign of building intimacy.
If it makes you uncomfortable though you have the right to set your boundary and ask him to work through it with am IC instead.
