An intervention would be the the same either sex. My suggestion would be to leave and if that is not possible, take the same steps a women would take i.e. counseling etc..via church family or other professionals. No matter what the person has to do something.
In my line of work, I do come across males that are victims and they are very hesitant to come forward because of the stigma attached to males admitting they are victims. Please know, the tolerance for women that assault me is the same as if it was the other way around. Hey, if they strike back, she is only going to call he police and have him arrested for assault. Crazy, is crazy...things have to change or that person has to leave the foolishness.
