Maybe you and your husband, and some other of her friends, could all chip in and send her to a Model Mugging
course, so she can learn to deliver a knockout blow to an assailant. I attended only a graduation a long time ago and learned a lot just from that, taking a course would be a good investment. They even teach them how to deal with assailants who are under the influence of drugs or alcohol, which affects their responses. You say you took a self-defense class yourself, I would hope you found it useful - perhaps sending her to one would be a better investment of time and energy than guarding her every night (and the sex), especially if she is feeling disempowered by her ex's assholish treatment of her. It might really help her self-esteem in a more lasting way than getting it on with your hubs or anyone else would.
