Quandry

What do you do when you think one of your friends is lying to you, but you aren't sure? Confront them and in doing so, reveal your source, thus ending not one, but two friendships? Ignore it, and hope the gnawing feeling in the pit of your stomach goes away and that you were wrong. Is it possible to tell a friend that you would rather have the truth and hurt feelings than be lied to? I just don't know.
