If a guy never compliments you, does that mean he's not interested?

If a guy never compliments you, does that mean he's not interested? This guy I'm seeing, shows signs that he's interested in me long term, talking about the future etc, but he never compliments me, or says things like 'hey beautiful'.

The closest to a compliment he's ever given me, was when he said that his auntie thinks I'm very very beautiful.
