I remember watching Breaking Bad for the first time when I was like 14 and thinking the same things and generally believing Walter White had his family's interests at heart.

But then I rewatched it as an adult, and I can't believe I felt that way. Now all I can see is a lying, gaslighting, abusive piece of shit putting his entire family in danger so he can LARP as Pablo Escobar. He constantly tells Skyler they are not in danger even as he is looking for ways to kill Gus before Gus kills them.

Skyler is basically a hostage throughout this entire thing, having no choice but to live with this man who she comes to despise. And she didn't cheat on him. She had at that point made it explicitly clear to Walt that their relationship was through.
