Iacrsmma: “And the person suddenly became physically abusive while pregnant with #9?”
Likely not. By #9 she couldn’t take it anymore and finally had the support/resources/koach to help herself and children. Maybe she didn’t want #9 to live through it.
Furthermore, abuse can escalate. The controlling behavior in early marriage can turn to harsher levels of abuse. Anything is possible and so common unfortunately that imho it’s alarming how much people are kept in the dark about it.
