Scared to add someone from my past.

Recently made a FB and found someone I used to be involved with.

We ended on bad terms- he just stopped speaking to me for some reason and it broke my heart.

It’s been about eight years since we even saw each other. I wonder if I should add him but I’m scared of the rejection- it would hurt worse than how things already ended. What would you do?

Edit: some of you don’t quite understand. We were casually dating and it wasn’t that serious. He didn’t know the extent of my feelings because I never got a chance to tell him. We both got incredibly busy and I guess I hoped I was more important but I understood why it fizzled out. He’s still single and we had a good thing going.
