hi everyone. recently i met someone online by the name of evan hudson. we got along for awhile and then he started to get mean. lately he has become increasingly hostile towards me. he has sent me an email stating that he knows my ip and that he can do lots of stuff with it. i am worried that he will be able to track down my location and hurt me. are there any ways that i can protect myself so that he doesnt try to find out where i live and try to hurt me? also is there anything that i can do to physically protect me?
