When it comes to infidelity of their spouse why more women are deciding to forgive?

I believe it is the forgiving heart of a woman. They have the maternal instinct and love. I also believe that the female tends to have a softer heart.

It could be that the woman loves her man so much, she will do anything to keep him, including forgiving him to his infidelity.

Yes, such could be the case. It could also be that the economy is so bad that sticking with an errant husband is better than trying to make a living alone. It could also be that more women are cheating on their husbands and have to admit that what is sauce for the goose is also sauce for the gander.
