I agree with the others. Kind of like he did at the game, they have a way of finding you if they want to. Let him pursue or run away, but give both of you the space. If you don't, it'll be like tangling with a meat grinder.
As for FB. It seems to me that a lot of people use that as a kind of tool. They use it to show how "happy" they are, or how "great" things are. They also use it to spy on people and gather intelligence about them. My suggestion is that if YOU are not ready for him to be on your page and watch what you post, then don't accept the friend request. You can always let him know it's for you that you make that choice (later and only if he asks.)
Be honest with all you do. It's never a good idea to do things to get his attention or to prove how happy you are etc. You'll be tempted at some point. They have a tendency to try and get your attention like a teen - often with taunting or anger. The response is to try and defend yourself. Try not to get caught up in that. Silence is a great answer if he is being unkind in his attempts to interact.
Why? Because he'll twist whatever you say into something like "see?!! that's why I left!" If you misrepresent or defend, that's the fodder he'll use. I saw a lot of that in my case and in many others. In my case, it took a long time before that sunk in with me. The other reason is because it helps you to get perspective if you detach from that kind of stuff and only pay attention to the polite and respectful interactions. And finally, because it "teaches" others how to treat you. Some need that more than others
Based on what you say above, compassion shouldn't be tough. But it will be if you take the bait with future interactions. They may escalate the more you don't take the bait, but stay the course. It'll be worth it.
