40 is young. You have realized that you don't NEED someone else for your happiness, but I'm sure you understand that people can ADD to your happiness. And if someone by their decision does not want to SHARE that with you, then they need to go.
See it's not always about what someone gives YOU. It's about what you two share.
I wish you the best, and somewhere out there are some supportive relationship partners who'd love somone like you and want to SHARE with you.
