I...wat. I'm kind of thankful the show put off a strong enough vibe of 'nope' for me after the first episode that I stopped watching. Cheating is BS. Running away from your supposed SO because you can't handle your own problems is BS. I'm in kind of a grey area with slut-shaming, so I can't really comment there, but they could have done almost anything else to make the new guy a bad choice for her.
