I know what you mean. A person I know was constantly messing around with "worldly" women while married to a JW wife. Of course as a wealthy contributor to the local KH he got away with it and his wife got DF'd for leaving him.
He was introduced to and dating his next JW wife within two weeks. Married soon after. And promptly started fooling around on her too.
He was rapidly promoted to menstrual serpent, and now is an elder. still fooling around, and getting drunk regularly.
