1 yr ago, an acquaintance of mine gave my number to a guy.At first, it wasn't so bad as I already met him before and he seems nice but then he suddenly started to call me every hour, sent me messages more frequently and be upset that I don't get to answer at times.I drew the line when he called me drunk wanting to talk to me.The day after when I continue to receive messages, I told him again to please stop contacting but he didn't.At first he said, I was being immature about this(he was 5 years older than me) then he said he was sorry that he fell in love with me after breaking up with his fiance and its not his fault that he wanted to tell that to me before he needed to leave as his visa was expiring.I changed my number and avoided places I usually frequent.Those times, were really scary for me.Unfortunately, I live in a place where most everybody know each other.I am going to be a host in a celebration tomorrow and I just found out that he might be there as he married the closed friend the party is going to be for. What should I do? Im scared...Do you think he changed?
