what do you mean though, is he constantly texting you? Or keeps talking to you in public? If it's through the phone, block him, if it's on person then very clearly and loudly tell him to leave you alone, he won't want that unwanted attention

if he approaches you, don't ask to be left alone. Tell him to leave you alone, even if you get called a bitch for it. had a similar experience and I made myself clear. left me alone.
