I'm sure that the previous posts about him not wanting to be disrespectful toward another family member is true, so try not to over think that, or perhaps he was answering it in a closed way because he wants you to think for yourself, and make you own academic decision? My advice would be to speak to him, or if not your Mother, about how you are feeling, because it might just be that he feels this way about you but also doesn't feel comfortable expressing his affection, for whatever reason.
