Not if she has any spare brain cells at all!
Look,the whole fidelity thing went down the drain during the Sixties sexual revolution of which I regrettably admit I was a big advocate of back then.
Too bad because even though the monogamy of my parent's era-with many exceptions even back then,of course-seemed boring at least you felt you could trust your wife or husband not to act like a total whore.
I talked a good game back then but in practice I was generally pretty faithful to whoever I was with.Yet seeing all the cheating and promiscuity around me completely soured me on ever trusting women again.
And If I was a woman,no way in the world would I trust a man!!
