Does he or does he not...

Does he know she's playing him out or he has no clue at all?
Or is it the situation that he knows but he's playing dumb about it?

I really have no idea what to do. Guess the best thing for me is to continue playing dumb. That's what I do best, it seems.
But it's hard. Knowing that at the end of the day, someone will inevitably get hurt.

Maybe that's why I don't want a relationship. It hurts too much at times. And I have enough emotional and physical bagguage of my own to want to carry another.
