Es una roba maridos

[ROBINDESBOIS]

In English?

O lo que es lo mismo, es una ladrona de marido = une voleusse de maris

[Nico]

In the U.S. the most common word I have used is a home-wrecker, which is more than likely slang.

[María José]

I do agree, Nico. There is another related word that can be used in a more general context (the guy doesn't have to be married): man-eater.
And one more thing: the wife would probably refer to the home-wrecker simply as 'that bitch'.:D

[CrOtALiTo]

I have another idea about the as you could to say it in another term.

Women destroy families.

This example is more simple but I believe that it gives you the idea about that it's talking about in the context more serious of the real life.
