Ending a loving marriage because we can't agree about children. Am I making a mistake?

I 35 (M) met my wife 34 (F) when I was 26. At that time I was young enough that I didn't really think about children. We both weren't really sure. As time went on I became certain I wanted children. Both my brother and sister had kids, many of my friends started having kids. I became sure that it is something I wanted. My wife became certain that it was something she did not want.

Things fell into place in other aspects. I have a 6 figure job where I only work 2-3 days a week, rental properties, and money saved. While I don't consider myself rich, I am doing better than alot of my millennial peers. We travel regularly and live comfortably enough. My wife works but does not make close to what I make.

Things are in place that we can afford to raise children comfortably. My wife wants to live child free. She does not see any real positives to having children and wants to just focus on us enjoying life. This disagreement has caused problems.

We both still love each other but we realize we can no longer be together. I can lie to myself and say I can be happy and fulfilled child free but I would eventually grow to resent her. We decided that it's best we split up.

Of course it's not easy because there is still alot of love. I worry that even if I leave her and try to find another woman that shares my goals I may still end up child free. I would have then left the woman I love so much.

She is amazing. Even in divorce she is not trying to take half the stuff. She is not going after my rental properties or savings because she said it would not be right to take what I paid for. She only wants part of the money from when we sell the primary residence.

Some of my friends say I am making a mistake. I am demanding too much. They tell me that I already have financial security, a loving wife, and a great career and should be happy with that. Of course they have children, their unhappiness is because they don't have the financial security.

It would have been easier had one of us cheated or had one of us just stopped loving the other. Ending a loving marriage hurts so much more.
