Most Helpful Guy
'He is so cold and standoffish towards me. I realise that I hurt him & I was deeply sorry for that."
Sometimes being sorry isn't enough. You destroyed his world, and left him to pick up the pieces. It's a hard road to get past that, and once you do, you don't really want to risk that kind of devastation again.
You hurt him once, what's to stop you from doing it again?
