Responsibility? Let's try this. In the Catholic Church if just ONE partner, male or female, practices birth-control, and the other is aware of it, then they are BOTH guilty of birth control (at least it used to be that way). So, they both are living in sin.
IF the couple agree to an abortion, then they are BOTH guilty.
I don't like the idea of the biological father not being informed of a pending abortion, or not being considered. Yes, I agree the father should have a right to be involved in whatever action concerning abortion is contemplated. It's his unborn child too.

Now, hopefully one day everyone will realize that killing babies is just wrong..plain and simple. Wrong. And should not be done.
