Safety first! Stop teaching in the neighbourhood he lives. Stop immediately. I know you need to support your self financially n is hard to get a job. But, u know what some ppl are capable of , right? U are so young and won’t be able to defend ur self physically if he ever decides to assault u. So, do ur self a favour and stop going there. I don’t think he can come to ur dorm. If he calls, don’t answer. He can’t confront u in person. Protect your self, girl.
