Ellie - that is neat that you went to your H afterwards. I think another hard part for me is that the slutty person in the movie (who was stealing the husband) reminds me of how ex-OW is - though I'm not sure that ex-OW is that forward, I think she likes to make the guys think they have the power (yeah, RIGHT!). Plus both are British to boot.
However - I do think that the movie shows that a relationship between husband and wife doesn't have to be bad...just older and too familiar, for someone to stray. I notice so many people here who blame themselves up and down when it isn't that they've necessarily done anything wrong. Just like the movie Unfaithful - the marriage wasn't a bad one. It was just that the newer person offered more excitement.
I loved the film though (both Love, Actually and Unfaithful).
