I think that that was the woman's distorted "reasoning," not Brooks'.
But she claimed an abortion to win his love --- I wonder why she thought it would --- maybe she first claimed to be pregnant -- and he didn't like that so she claimed an abortion to win his love.
If he's having sex with a woman before he knew her very well --- he shouldn't be too surprised she over reacts to being dumped. Same goes for women. It's like Fatal Attraction --- some people overreact to being used just for a little hot sex.
