Therapy costs money too and she will need it when she is fleeing the abuse. Having a cash stash just in case, that's not big enough to be illegal or "hiding assets" but is enough to walk out the first time he hits her, instead of getting trapped into a cycle of abuse that leads to her death, is prudent for any woman. You're definitely speaking from a man's lived experience but just because you've never been made aware of it doesn't mean it's not all around you. Women literally put their life on the line in most heterosexual relationships. The person most likely to harm or kill a woman is not a stranger but her husband or boyfriend. And it's often the man who most vehemently argues against the idea, and says the woman is doing something wrong by hiding money, that she's not trusting enough or wanting to cheat, who will violently turn on her in rage one day for those same imagined affronts to his ownership of her. Which he'll deny right up to, and even after he does it. You want loyal, get a dog. Having a chance to escape is what makes staying a free choice.
