Mind. Blown. But we still hate our ex.

So normally, most people just claim "they were super drunk" and that they "made a huge mistake" and that cheating is just a one-off, hormone-based mistake. 

But while that might work in the movies, real life is a whole lot realer. Thankfully, someone recently put together a video that digs into what actually makes people go through with cheating. 

It's totally not trying to get their rocks off, as it turns out. 

Communication is the key to a good relationship? You don't say … we'll have to try that sometime.
