After re-reading you post, it appears you have already made up your mind not to allow the relationship to advance further beyond friendship, and if that is the case, I commend you for that. Personally, I honestly think you should cut off the relationship completely.

But the real question is are you ok with it. Are you ok having a continuing relationship with someone you know you are attracted to, who you know is attracted to you, but that should never go further? And are you sure, knowing how you feel about him, that you can maintain your distance? Because if you can't, I guarantee you he will take whatever you end up being willing to give. You need to decide if you are going to be able to shift it back to a straight friendship and keep it there. You also need to decide if this status-quo sort of relationship is going to prevent you from finding or falling for anyone else.
