The Year of Living Dangeourously

I just finished reading "The Year of Living Dangerously" by Christopher Koch and I have to say, I didn't love it. In fact, I've been dragging my arse since before Christmas. I loved the character of Billy but it was a bit of a tepid story all in all. I mean, Jill gets pregnant and decides to have an abortion in Singapore - Hamilton, upon nearly losing her (and the baby), realises that he loves her. For pete's sake, is Koch saying that if Jill wasn't pregnant, Hamilton would not have been concerned?? It just seemed a little contrived to me.
