Agree completely with Foxmoth, tell him to bugger off and stick his ego where the sun don't shine...... People like him are the reason GA is in decline and students give up.
Hours to solo has NO relevance on flying ability at all. I have seen students take over 50hrs to solo and go onto be first class pilots.
Just go with it, change your Instructor if needed and persevere, you will look back wondering what all the fuss is about!!!
