I'd rather leave personally, but what does that say about a person that gets cheated on? Why do they never consider themselves part of the reason their partner strayed. I know a female that acts like a total cunt and all of her boyfriends cheated on her...but she doesn't think she contributed to the problem in any way. How many times does a person get their phone stolen on the train before they say "maybe I should stop falling asleep with my phone in my hand",
IMO, only the cheater is at fault and not the other mate. Monogamy is only something that many societies follow based on whatever concept or belief.
In a day of age where cheating or infidelity is easier than ever, people would be better off being honest all the time. The problem with people is society says one thing, but our own personal desires says another. Some people get married due to the pressures of society, family and friends. But so many people lie to themselves because they know that temptation is something they are weak at. The person that gets cheated on will truly never know exactly why they got cheated on and will look for answers that will never be good enough. There are hundreds of reasons and factors why people cheat or why people gets cheated on. Think about how infidelity can be as traumatic as a rape victim. I don't think I am reaching when I say that, but most of everyone in this thread has been cheated on that caused them to completely change or alter their perspective about relationships and people. Many times it has a long term effect and usually carries into the next relationship.
