It is natural for a fitness instructor to be handsome, and women will be attracted to such men. But like it or not, this kind of man has more contact with women and more philandering. He is kind to you for a purpose. In order to earn your money and improve your popularity, he will be very good to every girl. Don't think too much. If you really can't extricate yourself, give a hint and see how he reacts. If he has feelings for you, he can develop. But don't get too deep and make yourself miserable!
