Spidey, I never said anything
like that. Here's what I wrote in my initial post on this subject:
So, I was talking about relationships in which abuse was already ongoing.
As coilynapp has pointed out, pregnancy is statistically a dangerous time for abused women. There is also a great deal of research on causation. These studies show that (a) many abusers behave more abusively in direct response to pregnancy, and (b) they do so because they perceive it as a challenge to their control over, and access to, their victims.
