I swear I have a love-hate thing going on with Cayden. I admired the fact that he broke up with Aliyah for what he perceived to be her good. Whether or not it might have been misguided, he was at least motivated by his love for her to do what he thought was in her best interest. Chalk up one point for being noble and unselfish.
I was on the fence about him marrying Bindi. I mean he certainly is deserving of happiness, as is she, so it had the potential to be a good thing. I chose to believe he married her looking for something positive in his own life rather than out of spite because he couldn't have his true love, Aliyah.
Now I think he is an absolute skunk for lying to Bindi and treating her like garbage. I understand he's had a hard life and all, but that is never an excuse to abuse someone else. He's going to have to work really hard to redeem himself in my eyes.
