How to know whether Aries man likes you as in love interest

I have a friend who is an aries man he constantly teases me, does silly fights, always up for me to take on a bike rides One time in our group some guy texted he wanted to become my close friend and the next day this Aries guy was just sitting so silently not talking to anyone ( he is bit introvert and me being a gemini im extrovert) When i asked why are u so quite he just said i don't like anyone I don't wanna talk to anyone here And I am confused whether he has a feelings for me or not
