If this person is really hassling you, you need to make it clear that you are not interested.
I understand that you probably don't want to hurt his feelings, but you could explain that he is damaging any possible friendship by crowding and hassling you.
If he texts - don't text back.
If he is calling you try not to answer, or get someone to say you are not there.
Let your friends know how you feel, especially if he's making you uncomfortable. If you don't want to be alone with him make sure you have a friend around. They don't have to 'babysit' you but it might make him feel more apprehensive about approaching you.
If you feel that he is hassling too much make sure you tell someone and most importantly HIM! Don't feel like you have to be nice if it is getting too much. Explain you're flattered but not interested, and won't ever be. Suggest that he finds someone else that likes him. It'd be better for him and you!
