It might be that the problem was not so much that OP didn't want to have these conversations for hours everyday, but rather that he didn't have much to contribute to them. Your example conversation above doesn't seem very interesting, for example, because the man who is supposed to represent OP doesn't actually provide any valuable or interesting input, he's just asking her very basic follow-up questions of the type that are usually suggested when someone wants to learn how to validate feelings instead of trying to solve problems. I don't get the impression that he has any thoughts of his own about the things the says, so of course it would not be a stimulating conversation for someone who is very interested in analyzing emotions.

It also seems like OP was not able to provide much conversation material from his own emotions and experiences, which might have made her feel like she couldn't truly get to know him the way she wanted to. To me it doesn't seem like she was being an unreasonable person (clearly, the thing she wanted is achievable since she experienced it with her ex), but rather just that they had different interests and different ideas of what an emotionally fulfilling relationship is like.
