Glad I went back and read the thread. So many people supportive of the idea that men are not the only abusers out there. But here, very clearly, you answer your own question.
This in spades. You are not her White Knight, her savior. I made the mistake in my marriage of trying to be this from time to time. I learned that some people need their burdens, and if any of them are lifted, they will not only create new ones to take their place, but if you willingly shift their burdens to yourself, they will willingly shift the blame to you as well. Be careful of this trap.
Also, do not reinforce or take on the idea of “men = abusers”, lest you become one in her eyes as well and/or reinforce destructive hatred of all men.
Anger is a powerful evolutionary tool. As I’ve said, anger comes from fear, which comes from powerlessness. Anger helps us reclaim our power. Unfortunately, anger also tends to stomp the fuck out of our moral compass and claim power over us by being thoroughly addicting. It feels good to experience power by being angry (hence the age of recreational outrage on the Internet). But in the end, used too much or lived in too well, it warps and destroys you. It makes YOU the monster.
Many years ago, a then-friend of mine was robbed at gunpoint by a black drug dealer, and then forced to drive the guy around for several hours while the guy did his deals. He became very racist against black people because of it.
What happens is that the victim identifies their assailant as a member of a group, and then transfers their anger to the entire group of potential assailants. Their anger isn’t enough to regain power against that one person who wronged them, so it becomes hatred and irrational anger against people who have fuck all to do with the original situation, as a means of attempting to regain power and protect themselves against it happening again.
Hating all men (or women), or all black people (or all white people), or all left handed bowlers, isn’t going to protect you from danger, or make you safe, or give you power, or make you happy. It’s going to fuck you up.
