so today some guy who I thought was my friend started calling me a slut a bitch and so forth and so on. All this because I didn't want to mess around with him. He told me that I was a whore and only wanted to use people for sex and all. Funny since I was the one who didn't want to fool around with him. So he even brought his friend into it calling my best friend on her phone ugly and a bitch and so much more. I took this to someone and I actually have a lot of people on my side, but this doesn't stop all the facts that I might have been able to prevent this. I need some advice?
