How To Treat A Woman

In, a woman 'splains to men how to handle an unwanted pregnancy.

Coddle her:
You’ll also want to take care with your word choice; pregnant women tend to feel like they’re carrying someone, as opposed to something, even if she is just a month or so pregnant. You can’t just talk about having an abortion the same way you’d talk about having a cavity filled. Sensitivity is key. Toss words like “it” around too many times, and she’s going to start feeling like she needs to defend “it” from you.
Treat her like a child.
She needs your emotional support or she could wind up feeling isolated to the point of despair -- and women in despair rarely make rational decisions.

Manipulate and threaten til she gives in:
You’ll probably want to provide for your child regardless, but if you’ve been clear about your intentions from the start, you are not obligated to contribute beyond what your conscience and the law expects of you. This was her decision, not yours, and the bulk of the responsibility is now hers.

Prenatal pros: Take a moment to spell this out for her when she gives you the final decision; it may just sway her over to your side.
Ah, pro-choice Sisterhood. The dignity! The respect!
