You probably not a friend to him, just a way to get attention and maybe sex. Block him because of that.
Block him because you try to compensate your bottomless pit where your heart once were.
Block him because he uses you as a way to boost his ego.
Just block him.
Move on, either towards your solitude in loneliness, or actions towards finding partnership. Either way block him.
You don't really need him, and he don't really need you.
This won't really help you with feelings of loneliness, but do remember that you always have us, 24/7 available to talk to you and share your feelings with.
