I totally agree, I couldn't stand Sadie and have minimal patience about relationships based on miscommunications. I also felt like there was some apologist writing for Dov? There was an undercurrent of, well Dov's an abusive asshole, but at least he's brilliant, and Dov sticks around for the entire book for the purpose of continuing to provide brilliant tidbits.

The main thing I loved was the exploration of a creative work relationship/friendship, which is not generally the type of relationship that fiction explores. And maybe it's realistic in such a relationship that there would be miscommunication and jealousy.

Wait, did Sam confess that he loved Sadie? I read it as, he was jealous of Marx and Sadie's relationship in the way that many of us might be at first when two of our best friends start dating each other. I thought he was actually asexual.
