When emotional abuse escalates into physical abuse, there are usually signs along the way that the other person is violent. If this is the case, it can be too risky to stand up to this kind of person. So I wouldn't recommend it. But a woman can still take a stand by leaving the relationship, by insisting they seek therapy , etc. If there have been no signs of violence, most women are safe in taking a stand.
Emotional abusers push their limits.
They will go as far as their partner will allow. When they learn their partner will no longer allow it, some will back off. Others may try different tactics. Still, it is worth the risk. Many emotional abusers don't even know they are being abusive.
