I'm sorry...but River is the epitome of why I loath Moffat's portrayal of women. She's not strong, she's not well developed, she just smirks and simpers about "spoilers".
She's not well developed - yet. We know as much about her as the Doctor does at this point (although why he doesn't just google her in the 51st century and find out all he wants to know is beyond me). We don't know that she is his wife, but she is obviously someone the Doctor loves and values, so much so that he ensures her essence will survive in the Library when her physical body dies. IMO, that says a lot about her character. She's his intellectual equal, often being the only person who can understand what he's talking about. From what little we've been told it seems she does have a life and career independent of the Doctor, but that he keeps coming back periodically for visits, which he doesn't do for any of his former companions. As for "spoilers", she's probably doing it as payback to him for doing it to her, which he does to her because she did it to him, etc. Timey-wimey antagonism.
