Splitting up happens even for married couple. Young, old, cheaters or not. I wasn't referring to any specific type of people, os. But there are plenty topics here that examplifies why marriage isn't as appealing as it should be. I'm just saying that the sanctity of marriage has been desecrated by the selfishness, childishness, and irresponsible character of those who are married.
You may think you are better off being married and miserable rather than single and miserable but you're not.
I also don't believe someone who cheats will suddenly stop cheating just because they are married.
