"Unbelievable vitriol"???? What the fuck.
No, I don't think all men are bastards, not by a long stretch.
I think all men who try to murder their wives are bastards - and yes, that includes your husband.
You are trying to justify the dangerous risk you have taken with your and your children's lives by attempting to put another woman into the same situation as you. If you can persuade her that it's not so bad, it will make you feel better for your own choices.
It's reprehensible behaviour on your part. Because it really is that bad.
Did your husband leave the house when he was "horrified" by his violence towards you? Did he have himself sectioned? Did he encourage you to report him to the police, or report himself to the police? Did he find psychiatric support immediately? Is he engaged in long term therapy? Has he done anything at all to warrant your trust in him after he tried to kill you?
I'm pretty sure a therapist or psychiatrist wouldn't dismiss his violence as a "one off". And if police knew, social services would have been involved to try to protect your children. So really, the situation is that your husband tried to kill you, you forgave him on behalf of yourself and your children, you continue to live with him in the hope that it won't happen again, and he has done fuck all to show you that you can trust him in that respect.
And you KNOW that's not right. But instead of confronting it, you try to make yourself feel better by spinning this story about how it can be a "one off" and how women are all vicious manhaters.
Is it working? Are you feeling better? Jesus, I actually feel more sorry for you than I do for the OP. At least the OP knows what's happened to her is wrong and isn't trying to inflict it on anyone else.
