Impossible that that happened. One of you blocked eachother.

Facebook doesn't block people unless there is a complaint filed. So, either one of you (or your parents) filed a complaint, or one or both of you blocked each other.

Facebook doesn't block people unless they receive complaints.
Maybe someone reported one of you or else one of you blocked each other.
