Everyone has their own limits and ideas on what constitutes cheating and I want to know What defines cheating? I understand there is emotional and physical cheating my question is what is immediately a deal breaker? What is " attempted cheating " and could be worked through? Example : for me some hidden chats or something that implies they may be setting up a possible affair may be worked through but multiple offenses means break up. However if the chats seems more than just a flirt and well, sexual nature, and it turns out her they are " in love " the that's a deal breaker. If my woman just goes and sleeps with an ex or just some random can't control yourself sexcapade there is no reconciliation , done right there. And as far as swinging relationship s or that type of relationship what personal rules have to be broken to consider it cheating where otherwise it is mutual condoned fun ? Also , what would count as a shady circumstance? How many shady occurrences before there is a confrontation? What would be your reaction if you come across a genital pic your SO sent to someone besides yourself?
