no, people stay together past the point of passion because the power structure that they are in demands it pure and simple, too much at risk to separate, the thought of it causes too much anxiety, regardless of sex. And if a man is weak like you said, gentle guy = pussy, no the woman does not love him, when she has sex with him he is far from her mind. She can't help it, he doesn turn her on therefore she is not in love. She has some loyalty, she calls it love, but really he's her little puppy, these men eat a lot of pussy lol
