Most domestic abuse starts with the woman nagging the guy into a corner, so where he is damned if does, damned if he doesn't, and damned if he does nothing. So, after she cuts off all the speaking routes to come to a solution, what is left?

Unfortunately guys are not usually taught about this women's logic word salad that binds.

The correct response is to say, "Don't ever do that again, or else". And as soon as it is broken once, leave.
The relationship is over, she does not respect you, and a woman's love is based on respect.

Too bad that women think they can do cheating light.
Kissing, teasing, dancing on a pole are all "not" cheating in their eyes.

But, to a guy, those are all cheating.
Or in other terms, his woman is becoming less valuable by the minute... and that is theft.
