In the opening scene she seemed really warm and caring, with all the food preparations and everything, but then she started bemoaning her son marrying a widow, and that was pretty early. I also really didn't like the way she treated Atsushi. At least the father/grandfather was more welcoming of him, in the scene with the two of them in the exam room. I definitely felt more sympathy for her husband than her, but at the same time he was rather cruel to Ryota in how he constantly held Junpei's up (his heir) and never really accepted Ryota as good enough.
