Is it a crush or love?

So I recently transferred to a new school, and met this awesome guy, lets call him J. So J and I hang out all the time between classes and we hug and mess with each other and such, but recently all of our teachers think we're dating and I've begun to have feelings for him and he has begun to like me too, (his friends and he told me this) but these feelings between me and J are really strong, like even his ex (who I'm besties with by the way) agrees that we would be ADORABLE together. Should we start dating? (my parents are against this)

Is it a crush or love?
