If you think that your partner has been cheating, then take a look at their will. If a past lover is in there, then it is probable that some form of infidelity has occurred.

Like the moon shining bright Up high with all its grace,I can only show you at night And hide half of my face.

Cheat, defeat, repeat.

Deceivers shall always be at the junction of double mindedness.

It will always be foolish to ask a cheater if they would ever cheat on you.
