Is this morally right or wrong : for a woman to maintain close platonic friendship with a married man?

I would say we are very emotional people and sometimes our emotions override our thought process. We don't take into account how our actions may cause other harm. The two people are only thinking of themselves. Both people seem lonely. The man is without his wife, and the woman is not in a relationship. The two have taken comfort with each other, and I believe it has turned into something more than just being friends. I think the two people need to take in account their relationship, and the other people around them.
