To me I would say it's the cheating partner that has to be blaimed. If he/she truly love his or her spouse then I see no reason while the person should go out cheating.

Even in most cases I don't blame the single ladies or men. Why??
Some of the cheating partner comes to them in the name of true love main while it's lust covered in the name of love.

The cheating partner should be the one to be corrected. He or she should know his married. If he or she feels the spouse isn't giving it to him or he to satisfaction then they should seat down together and talk things out rather than going outside in such cases.
