Authors note: I have gotten a couple of reviews from guests regarding the concern that Derek would never cheat because he knows the pain and ive ruined MerDer cause meredith would never forgive him etc just to say this is simply a story that I had in mind im not trying to 'ruin' merder! I love merder! It's the reason I watch greys haha! Also for arguments sake I will clarify the background to this story , Derek was never married to Addison so the cheating never happened between mark and her if it would be easier I could write a side fic of what I had in mind for how Derek came to being in seattle if that would help people understand this story better. Further more addressing the whole "he wouldn't do that to mer" well he left her for Addison which im pretty sure must have hurt like a bitch , and to address the "mer wont forgive him" Meredith is a complex person with complex emotions but she is also forgiving we've seen that in so many episodes! So please when reading this do so with an open mind. Other than that thank you for the positive reviews from the rest of you!
