Meg, here's a dramatic case for your files.
My wife had twins three and a half years ago. She had pre-eclampsia before they were born and had to be hospitalized. She nearly died while giving birth to them and was further hospitalized for weeks afterward. She came within a hair's breadth of dying.
While she was in the hospital, I took care of the twins. Exhausting work. No sleep.
Even with me arranging my work schedule to be home as much as possible, after four months we were both as tired as two human beings can get. And my wife was suffering from serious post-partum depression.
Then we found out she was pregnant again. We fell into the "no birth control" category since because of the complications of birthing the twins, she was not immediately able to return to the pill, and I simply cannot function with a condom.
Then I was laid off from my job. I was in the hi-tech field which had collapsed, and there were NO jobs to be found. And we lived in the state with the highest unemployment rate in the country.
We were living off the government, which doesn't provide anything close to what we needed. We were looking at losing our house, everything.
So we pretty much matched the top four or five or six reasons women get abortion over. In spades.
And many of our friends did not hesitate to suggest we get an abortion. To be honest, we did not receive the news of her pregnancy with any happiness. We were devastated. Shocked. Feeling really, really stupid. And tired. Oh my God, we were tired.
But the thought of abortion was out of the question.
I just put my nose to the grindstone. I went out and busted my ass and got a job in a totally different field, several months below the average unemployoment time, and way before anyone else in my company who was laid off got one.
Motivation.
That new baby is two and a half now. The twins are three and a half. We can't imagine what life would be like without any of them.
We're still pretty tired and we live paycheck to paycheck.
ETA: My wife has told me that even if she got pregnant from being raped, she wouldn't get an abortion.
Sometimes people forget some of the most avid pro-lifers are women.
