"I'm doing SO much better without you."
"I never needed you."
You're right. You never did.
And I'm proud of you for finding happiness without me. You never needed me for happiness.
So, I am happy you found happiness without me.
I never needed you, either.
I'm happy we both realized that we can be happy without each other.
We never needed each other. But we always wanted each other.
And I think that's often more important.
