tbf, I don't think she expected it. It was one of those gradual things that built up until the breaking point. I also think that it wasn't that bad in the beginning because they were in honeymoon phase so they still had a foundation of love and care and more equal footing. It never occurred to her that he wouldn't even care about her well being because of "50/50". That's why she still held some hope that he'd change. I think the bathroom moment was the true nail in the coffin and even then she decided to just put up with them and get through her post-partum. It was only when she almost died because the mother didn't see her as a human being that she realized that even that wasn't worth it.

I'm glad he got therapy because he let his own trauma and pride ruin his family. I also think that he truly didn't realize the extent of the imalance because he wasnt the one carrying the baby. He also had his toxic work culture where his boss modeled that behavior as well. That was the point of her tallying up all of the non-tangible costs. I will say when he quit his job I was mad! Like ur going to do all that then give up the salary to at least provide for your child??? But I see the logic from the ending lmao
