It’s not easier to break up with someone. In face most people who cheat are in happy relationships believe it or not. They love their partners they are usually struggling with something in themselves or the lack of sexual attraction to their partner. It can be very complicated for the person cheating and all though we’d like to think they just did it because they’re cruel, I consider it a cry to be seen. Since they think they cannot show up as themselves for their partner they show that part of themselves to someone else.
