Thread: Two Faced or Tactful?

I have an acquaintance, whom I work with. When you work with someone, you have to be tactful, even though you may personally can't stand this person. This person thinks they are my best-friend., and maybe its my fault for being tactful and friendly with her. It kills me even to talk to her, especially outside of work.
Now that I'm moving, she's heart-broken, I hear everyday how she doesn't know what she'll do without me, but in my mind I'm like I HATE YOU!
Is it wrong to put up this front that we're "friends" or should I tell her how I really feel.
Two-Faced or Tactful?
I guess she'll know either way, when I do move & block her from my phone.
