Who do you like better? Cathy or Jamie?

Cathy has quite a lot of flaws but cheating is inexcusable, I'm sorry. I thought both characters were on fair grounds, but when they showed him in bed with another women, I immediately jumped on Cathy's bandwagon. Cathy could be less nagging. Jamie could simply be there for her like he promised when she thought she did good in one of her auditions. It was a sad but realistic relationship.
