Skyler White deserves better - Breaking Bad

I personally never understood the Skyler White hate in Breaking Bad [SPOILERS] The show is supposed to be realistic in the way drugs effect everyone, y'know? There may be times where Skyler seems unreasonable or too nosy but at the beginning of the show she is pregnant and worried about her husband and her family so it's natural to be concerned about where your husband is, especially once you found out he has cancer. After she finds out about Walt's meth stuff her reaction to call for divorce and take the kids is reasonable, I know Walt's intentions at the beginning is to not be a financial burden to his family but at this point in the show he just wants to make his empire bigger and bigger. At one point she is helping Walter in his business with the money laundering, since she did want to use it for the family like Walt wanted her to do (like when they bought Walter Jr. a car). For the most part I believe Skyler White was justified in most of the decisions she made and I don't know how many people label her as a bitch, she was one of my favorite characters honestly. Thoughts?
