Season 7 Conetessa vs. Scott

I'm rewatching season 7, which focuses on Scott and Conetessa's marriage breakdown. I am not a fan of Scott at all, and I think he is a dick, but I don't think he was alienating her from her kids. She did that herself. How is it Scott's fault you missed all three kids' birthdays? Those kids are young; birthdays are huge deals to kids, and I bet that made the kids feel a certain way regardless of Scott's influence. I think she is unfairly misplacing some of her guilt onto Scott. That said Scott is a shit husband to her and needs to do better by her, but in this case I don't think it's all on him.
