She did what was right for the infant.
Reference comment about boys, please consider this: women have all the power, they can decide to murder their baby and he has no say. . .and maybe after being told they are irrelevant, no say so about the baby, maybe they are that way because they are marginalized and after a life of being told “my body my choice and you have no say so,” they get with the program.
Not excusing everything, but I think it is a complex issue.
In my eyes just stepping forward and stating that you are the father and offering to do what you can is the right thing. Even if you are denied your rights you have at least step forward and excepted your responsibility. That makes you more of a man then those who just wash their penis and walk away.
