Tough rumor situation?

Rumors cause breakups in friendships. Be direct and also inform her that you and your buddie don't believe what is being said. Back her up in her decision. The cold response tells me that the person was annoyed with "Tory's" presence and informing her that it is none of her business. Also, ask "Tory" what is going on, it does not hurt to ask her. If she trusts you she will tell you.
