Unpopular Opinion about River Song

I know some people think that the doctor didn’t truly care about her until 12, but I have to disagree. Yes, there were many moments with 11 where it didn’t seem real, but we have to remember he is still the Doctor. But you can tell they have moments, like when they are fighting the Silence together, or flirting, or when he heals her wrist. I think for the most part River confuses him, but he also kept putting off going to the singing towers of darillium. You can’t tell me that means nothing!
