Hitting her would reduce you to her level, and escalate the violence or her trying to hurt you even more, imo leaving would be the right thing to do, which you eventually did.
Also, getting her help....she is obviously not stable, something is wrong upstairs and she needs or needed, professional help....
Uh......so a knife attack isn't escalation enough? How much further escalation can the assault and attempted murder get? Perhaps he should have waited till she sunk her knife in his chest. Oh, I know. I'm just being a typical male-chauvinist pig. Girls are so defenseless. Same with lesbians. Anyone who is a member of the Democrat's protected class is harmless. It's those damned white middle-aged males that are always the threat.
You liberals are being sexist about this. Nobody has the right to try to murder someone in their sleep, regardless what their sex is. This is identity politics and political-correctness at it's worst.
Quite the Drama Queen there Mudwhistle....
If the knife attack happened, then of course he had to stop her.
But prior to that attack, he was unable to recognize that she had Postpartum Depression/Psychosis (as in Andrea Yates) and needed help, professional help.... Blue kept saying how she was normal, until post child.
Many men, like Andrea Yate's husband, fail to recognize how dangerous this condition can be, without proper treatment. He attributed it to the "move" out of State....but it wasn't....
It's better to have all of this come out in the open and discuss it, so more men are more aware of the condition and recognize it early on, before the knife attacks and drownings.
