people would rather lie and sneak around

Well yeah. That’s a lot more fun then a conversation. And if you don’t care about your relationship anyways, why does it matter how you end it really? Might as well cheat

Edit: okay I’m being downvoted so I should mention that I know this “breakup strategy” isn’t for everyone but if you don’t mind permenantly burning a bridge, to me there is no harm in it. As long as the person you are cheating on them with knows what you are doing and is okay with it
