I agree completely. The only time we ever see Remus even close to happy is when Teddy is born. At that point he's happy because of his son, not his wife (and has a few glasses of alcohol to boot).

To me it always seemed like Remus made so many excuses because he was too nice to outright reject her, & even that may not have worked. Plus we know that one of his biggest faults is that he wants to be liked.
