I didn't see the show, but my family has had it's fair share of stupid divorce problems. There are five kids in my family. I have two biological siblings and two step siblings that were raised the same house as I was. So, the five of us all come from divorced families. My parents don't like each other. My mother did nothing but slam my dad while I was growing up. I'm 29, and they still fight over who "gets me" for Christmas. My step-siblings' parents get along pretty well. But, the inlaws are HORRIBLE. My step-brother's inlaws haven't talked for about 23 years. When my SB got married, it was very stressful to even have her ex in the same room as she was in. My step-sister's inlaws don't get along either. It's been about 30 years since they got divorced, and my Step-sister and her husband aren't talked to very much by his mom because they talk to his dad and do things with him. His mom thinks his dad is evil and everyone should see that.
It's very very very sad. I don't care what happened in the divorce (in most of the cases above it was infidelity) No matter how much you may be hurting, it does nothing but hurt the child involved when the adult acts stupid!
