tell him nicely sister

expess to him that u dont feel the same way that he does. be polite tho.

Be honest with him.. tell him what you really feel.. tell him directly that you don't like him and tell him to find someone who can love him back. that's it!

tell him you dont like him in that way and that you would like to only be friends with him. because i was in the same spot as you before and if you tell him that it should work

Just tell him that you don't feel the same way!

Be frank with with him, tell him that you cannot return the love that his feeling for you, tell him that if you can only teach your heart to love you but cannot be.

tell him to piss off
