There are what I would describe as psycho homewrecker lesbians who seem to enjoy the game of destroying heterosexual relationships. This happened to a friend of mine. The lesbian met my friend's wife at her workplace, developed a relationship with her, sexually seduced her, then convinced the wife to leave her husband and daughter.
Once the relationship between my friend and his wife was destroyed and they divorced, the lesbian lost interest in the former wife and began seeking new quarry, at which point the former wife realized that she had been manipulated by the lesbian. Her original marriage shipwrecked, she eventually entered into a new heterosexual relationship and eventually married a new guy. Her former husband had found a new girlfriend, whom he married. He is now on good terms with his ex-wife, solely as a friend now.
