How would you react if your woman surprised you with a abortion?

How would you feel if you were sleeping with a steady girlfriend for a year, everything was going great, moved in together, and one day you get back and see her sleeping early in bed. You crawl in under the covers and start running your fingers along her hips, and she lovingly rolls away from you, turning her back saying "Not tonight honey, I just had a abortion" and then falls asleep like nothing just happened.
