Kaylar -

In the movie Brokedown Palace, the opposite happens. A bloke gets involved with two best friends travelling in Thailand, seduces each of the separately, asks them to go to another country for the weekend with him for free, and they unknowingly bring drugs into the airport. The other girls he's already seduced are also in line at the airport, and they get through, but the two American girls get nabbed and thrown in prison.

I think anyone who makes a person feel like "somebody" - male or female, can easily manipulate them.

Sometimes the "other woman" is hearing how her boyfriend is legally separated, sleeping in another bedroom, hardly interacts with his wife, etc. to gain the sympathy and bodily access of said "other woman," when quite the opposite is true. My husband's ex-best friend did this to his "other woman" when none of it were true. I could never hate the girl he had an affair with (it felt unloyal to my friend, but I couldn't help it) because as P.T. Barnum said, "There's a sucker born every minute." She believed everything he said because he made for a very believable and sympathetic handsome wealthy guy. He was looking for a way out of his marriage and at home was keeping up all appearances to his wife, who was home with an infant and another on the way.

He caused a lot of heartache and financial problems for both women - he refused to give either up while telling each the other was out of his life - he's basically broke and living with mommy now, with neither his wife or girlfriend, but not before trying hard to get one or the other back.
