If I agree to adopt a child with a partner, I'm legally obligated to support the child, even if we break up. There's no biological bond, and parenthood is not all about biology. Why can't you see that there's no difference?

Once you have legally adopted a child, then you have accepted responsibility for the child. That is not what happened here.
