Is it bad that I don't do anything after school?

My boyfriend confronted me today that I don't really do anything after school and he's worried. I'm a junior and so is he. I did band for three years & stuff like that.

He said it's unhealthy for me to hang out with friends after school solely. I don't just do that, I go on runs, meditate, etc and I'm signing up for art classes. I'm perfectly happy and healthy the way I've lived my life and the way he's putting it is making me feel bad about myself. Is it bad that I don't play sports or do anything after school?
