So uh i'm genuinely curious on what other people think about my situation. this dude is stalking me he's been texting me and calling me non stop and has came to my house multiple times. what should i do?

For a stalker, your best bet is to inform people around you. Tell someone you trust like your parents, roommates, friends, security guards or your neighbors. Also don't try confronting him, if he is becoming to much, call the police, they would gladly take care of the problem. 

I also recommend investing in some form of protection; Pepper spray, Martial Arts, or a concealed weapon (if it is legal)
