Penultimate episode discussion

I’m on Blythe’s side here. We’re all human, and most of us have done things in our younger years that we’re not proud of. What matters is learning from those mistakes and moving forward, and that’s exactly what Blythe did.
I also don’t think it’s fair to label her a “cheater.” Both Blythe and Don were separated and seeing other people at the time. The difference is Blythe didn’t end up pregnant, while Don did get Dixie pregnant. Given that, I don’t think Don really has the right to be upset about Blythe being with someone else during their separation.
On top of that, Blythe even accepted Don’s son with Dixie, which says a lot about her character and willingness to move forward despite everything.
