It doesn't work that way.

I had a mentor once explain to me a wonderful example and you might like to use it as well, feel free:

The concept of love doesn't happen to us because of what a person does for us to make us love them but about what we do for them that allows us to love them. Same goes for parents, they love their child unconditionally not because of all that the child gives to them but because of all that you give to the child. If it were just about the tantrums, the crying, the getting up in the middle of the night, staying up all night to make sure their fever breaks, the acting out, talking back, etc. if it were just for those things then love would be hard but it isn't about what we get from children that makes us love them, it's about what we give to them that makes us love them.

If your husband is into cars then give him this example:

A guy buys a very old model of a nice car but it is completely trashed and he has to fix it up. Every Sunday he spends all day doing something to the car to fix it, new engine parts, new tires, new upholstery, new paint, everything and he can only work on it just a little bit at a time on his weekends because he works full time and can only give it limited attention so it takes a very long time, years even, to finally get this car top-notch and he even wants to show it off in a car show now! He loves that thing to death and is so proud of the way it turned out. He's spent so much time on it that it has a very special place in his heart. A friend of his asks him why he feels so attached to a car, it gives him nothing, it doesn't love him back, it can't do anything for him besides sit there and look pretty. He explained that he loves it because of all the time and energy he's invested into it.

I hope you find a way to communicate to your husband that just because he has resolved to feel a certain way now doesn't mean that he shouldn't allow room for his feelings to change, she's his child too now and she would be sad if he were to go.

Good luck to you.
