Carrie just lusted for Aiden. I mean look at him. Tall, dark rougid.
He was not marriage material because she was not intellectually challenged he did not like going out much like up town resturants clubs.
He was a nice simple guy, a home body. Low maintence. For example he'd rather eat a bucket of KFC and watch the game than go to a fancy resturant and eat designer food. Perhaps he would suit the older woman because he was happy to be at home and allow his lady to go out with friends. So that being said she would not have to worry about him cheating.
