....going out with somebody who's had an abortion?

I know everyone has got a past; but when I sat down one day with this girl im seeing just chatting --over a few drinks- last weekend, talking about her past relationship history she disclosed to me that three years ago, she fell pregnant and had abortion.. at two months into her pregnancy!

I mean, that just shook me so bad, i dont know whether i want to see her again, I mean, I'd rather be dating her now as a single mother rather than someone who killed a baby ...but am i over-reacting? The kid could have been two and half y.o. now, Geezus, this is hard for me to take..What do you think of people who've had arbotions in the past? First time i met someone who's had an arbotion, so forgive me if i sound a little weak!
