I think he wanted to play the part of someone who was torn but chose the honourable path in the end - hoping that would revive his popularity.
He messed that up when he said there was no attraction. Theres no coming back from that.
I dont like Amy. Because of her behaviour at the beginning. I also think she is quite needy and I dont like that quality in friends or partners.
I actually think she is quite vulnerable which is why Curtis has found her easy to play. However, I think she makes herself feel better by being a bit bitchy to other people.
I also dont like smug marrieds, which both her and Curtis definitely were.
However, I dont like the death threats or the constant comments about how she looks. She isnt the most stunning. But she isnt baby Jane either.
In my head I imagine, over baring parents that encouraged a life based around her looks and how much of a princess she was. She won pageants, had surgery made herself more aesthetic and still didnt find prince charming and her happy ever after and that's knocked her self esteem further.
Again, if she has never had a boyfriend or always second best, either theres something she is doing (I believe it's probably being too full on, too soon) or she is vulnerable and picks dodgy guys (like Curtis) again and again.
