What is it that makes cheating so enticing? You endure the ups and downs of the dating process in hopes of finding that one person that you've been looking for. Once you do, you're supposed to love and cherish what you two have together. If it works out, terrific; you can pop out a couple of children one day. If it doesn't, oh well, there's plenty more fish in the sea. There are fights, of course, but every relationship is supposed to have the ups and downs; that's what's supposed to make you stronger. But then comes the bigger issue: If you have everything you could want in a relationship, why would feel the need to find someone else? Why do they cheat?
In relationships, we all have the generalized criteria for what we need to feel validated in that relationship. Trust, positive communication, challenging one another, and security are some. Even though you perhaps have entered into a relationship where all of these criteria were originally being fulfilled, it's easy to either slack on your responsibilities of holding up your end of the bargain, or gradually start to feel your partner slipping. If that slip happens, what do you do? Do you argue constantly, nit-picking what's wrong with the other person? Or do you give up and find someone else? For some, that deficit in the criteria prompts them to seek something or someone to fill that void. Whether that may be relying more on key friendships, opening up your social circle, or abandon full reliance of the significant other and into other relationships. Through this process, the allure of misdeeds grows stronger.
Once at this point, a choice is to be made. Whether you consciously make the decision yourself, or the context of certain situations dictate the result, a turn of events is pending. Something about the human nature prompts us to continuously seek assurance from our significant other.
What we can learn from this is to make sure we are aware of our surroundings in a relationships. Keep the right amount of criteria in mind when dating, making sure those expectations are in check. Without doing so, you risk falling victim to your own nature to fulfill that criteria. If that's the case, you should not be in that relationship.
