Joliette,

I can understand that this guy bugs the heck out of you. Believe me...I get bugged by lots of different people, lol. I really think that the best idea would be to avoid him. Take him off your Facebook buddy page, so he doesn't have access. That's perfectly appropriate. He doesn't have to be allowed to your FB home page.

If the guy is simply present in one of the pages that you frequently visit, ignore it. Don't respond to text messages. If he asks why, when he sees you, just tell him that you're a little overwhelmed by all of the activity & aren't interested.

If when he sees you, he asks if something is wrong, say "No, not really." and walk away. If he follows you and keeps on your back, then tell him that you'd appreciate more space from him. At that point, it's appropriate to tell him to back off.

That's my advice anyway.
