Most people cheat on some level. There are many reasons why people cheat and there are many levels of cheating, but none of them are okay. Most are weak and can't resist temptations. It takes a lot to resist what you are wired to do.
I don't believe the whole once a cheater always a cheater thing. People change, but it's a red flag for future partners and it can destroy a relationship that is attempting to move past it.

Temptation, Lust, Sin. It is what it is. They don't care if you are loving, loyal and caring. They know this. And they also know your naive for being that way. They think like animals, so they will behave like animals. You can't change people who won't change themselves. Some of them don't want to change. They want their cake and eat it too because it's entitlement. Very few stray because they are being deceived by those who seduce them. That is why I say lust and seduction are evil. It also depends on what kind of relationship this is. Marriage or Dating? In dating, you should seek to date to marry. But since people don't believe in that hardly we have so many options that anybody can be a cheater. Even you. That's how bad it's getting.
