You could say politely "I don't think we have that much in common anymore, therefore I don't want to be friends with you anymore."
Tell them that you dont want to be there friend anymore
Then don't be his friend anymore.

* You need to communicate better with your friend as they may have a reason. Perhaps their parents have punished them from going out or, there could be other reasons. Phone your friend and meet with them and ask them why they won't come to your house anymore.
