Q : I would like to know the standard of judging on  infidelity.

A : When it comes to the husband's infidelity, there are cases of the husband saying that he only held hands or just had a little conversation, and so on. Problems occur because the standard whether he has an inappropriate relationship or not is looked for from these things. The standard must not be the husband who has had an inappropriate relationship with another woman but the wife who has figured out all of this. If she says it is infidelity, it is infidelity. The victim of the husband's infidelity, the wife, is the one who decides whether her spouse had infidelity or not.
