When Sally says to Bob at the end...
(after Bob comes home, and after he finds out about the affair) she tells him, "I love you"...does she? I never felt any love between the 2 of them. More of a marriage that they just got used to.
She just seemed really unassertive and assumed a very "wifey" role w/ Bob. He kind of molded her into submission. So, I don't see that as being love. And I KNOW she was crazy about Luke, but do you guys think she still actually LOVES Bob?
