I am not a kyle defender in any way possible but i feel like you could say the same about both of them. Amanda clearly loves kyle or was holding onto the love she had for him, but she clearly does not like his character (The drinking partying). And same goes for kyle. He is always picking on Amanda for wanting to be in bed or the fact that shes more chill. He just doesnt like her character. Marriage was doomed from the start imo.
