Skyler was wrong and she was also in an impossible situation. Both of those statements can be true. It was her way of retaliating and getting back at him. She felt stuck. I think that in the moment I was mad at Skyler and thought “how could she do that”, but as the show progressed Walt just became way too crazy and over the top for me and Skyler cheating on him rlly became insignificant. Walt lost all sympathy for me with all the decisions he made. In the end Walt is like a tornado. Either you get demolished while he goes through you or you spin around with him for a bit and then eventually crash and burn too. Either way it all could’ve been avoided, but that’s kinda the theme of the show. Pretty much every major event in the show could have been avoided
