OK kids, looks like i have to explain further. When you are in marriage, you might be unsatisfied. Sexually, personal attention and other such things. Which in no way means that you don't care about partner anymore. You have no intention to abandon current relationships. You just need some comparison, validation, second opinion. Now, ideally you go together to therapist and work it out, try new things. Not everyone have money for family therpist. Next best thing: you take a break and try dating other people. Very few can agree to this, becasue people tend to be naturally, biologically posessive of their partner. Reality is, cheating is much more socially acceptable, by everyone (invcluding unsuspecting victim), than open realtionships.
