Well, you had a good conversation. And he hit the ball that you served into his court.
Personally, I cannot relate to his belief that love is fireworks and excitement. That doesn't last in the longterm. That's like saying your comfortable pair of shoes should also stay looking like new. And if they don't, then they are no good.
There are other good things about longterm love beside fireworks. For example, you were right at his side a couple of weeks ago when he was in the ER. Surely, when you hold his hand it means more than if a new person holds his hand. I don't know if I can convey to you the pride you feel in your whole family when one of your kids graduates college, and you know that everything you and he did in the past 21 years led up to that point. Or when the kids are grown and talk late at night about their childhoods, and you laugh about just how funny your crazy, unique family unit is. These are experiences that you don't imagine until you experience them. But it is a wonderful kind of love you feel for the person who was with you all the way. If I had to share those moments with a new spouse, it would not be the same. But his feelings are his feelings, and logic doesn't make a difference.
If you were to tell him he had to move out until he figures out what he wants, I would expect him to discover that he wants his family. But I have never been good at predicting the future, so I am not suggesting that you do that.
