Which is worse, emotional cheating or physical?
Cheating is defined as doing anything of a sexual nature with someone other than your husband/wife without their approval and/or consent; and having deep feelings of care and love with someone other then your husband/wife without their approval and/or consent.
(Boyfriend/girlfriends do not count)
(Having lost their virginity before the marriage, masturbating with a dildo shaped as a different man's penis, thinking your spouse was dead, getting remarried and finding out they are actually alive, apply whatever else you want to the concept of cheating)
