Warning, this is just going to be a stream of consciousness comment about PF trying to paint KB as mentally unstable.
first off I will just say: gaslighting.
In MOO, he escalated to murder because (if I recall correctly) she had sought treatment for depression. For anyone familiar with abusers, gaslighting can push people to the brink of suicide/despondency. It can begin with simply moving someone’s car keys or phone, or saying “you forgot this”... And before you know it, you’re doubting every possible thing you thought, said or and did
Again, MOO, assuming she did go away for a couple weeks, away from his manipulations, I suspect, quickly realized she wasn’t losing her mind. She may have realized how abusive he was being.
I actually believe his intentions were to push her to suicide. When that didn’t work, he manipulated KK to help get rid of her.
I wonder if there might be any documentation that might show this to be true?
...and that probably made little sense! Haha
