There is mixed data on that. Sometimes the physical abuse might switch to emotional abuse or more physiological abuse. There's data that shows that. There's also data that shows there could be escalated abuse, both physical and emotional abuse. The studies aren't 100% conclusive on that.
There could be issues related to jealousy, related to changing body structure, related to women, the perception that women during pregnancy may not be able to do all of the things they could do previously physically.

That just happens to be the physiological effects of all the changes in hormones. I think all of those things together make women vulnerable.
