Infidelity is something that occurs so frequently nowadays that some actually believe they deserve praise for not cheating on their partner. Hooray! You totally deserve a cookie for doing what is expected of you in your exclusive partnership.

One time an ex-friend told me a story about how he hung out with his ex-girlfriend behind his current girlfriend's back because his ex was in town (they kept in touch from time to time). Long story short, he met up with his ex at a bar—of all places—and although she offered him sex, he declined.

What disgusted me—and still repulses me to this day—is how he claimed he was a great boyfriend for not having sex with his ex-girlfriend. Yup, you've earned the boyfriend of the year award for declining sex with not only someone who isn't your girlfriend, but your ex-girlfriend.

Some argue that cheating is perfectly normal and healthy for a relationship. Is cheating normal? Unfortunately, yes. Is it healthy? Not quite.

When it comes to cheating, the result of the relationship's status varies depending on your partner. Some people are more forgiving than others and can look past your moment(s) of infidelity—or weakness as I like to call it.

In many cases people forgive, but they can't forget. It's not easy to ignore the fact your partner hooked up with someone else. People say emotional cheating is far worse than physical cheating, but either way it's still painful to think about your significant other kissing—let alone having sex with—another person behind your back.

My advice, if you're incapable of getting over your partner's infidelity, you have to let them go. It's not healthy to stay in a relationship that causes you emotional pain every time you think about one moment in time no matter how much you love the person. Additionally, the trust issues that may develop as a result of infidelity are not only detrimental to the state of your relationship, but can cause your partner unnecessary stress.
