I have many friend. Some of those friends work in the same company together and know eachother. Other times I find out one of my friends for years is actually a firend of one of my friends from a previous job. In fact that just happened to me. A friend that worked in my local store and I were talking and I said one of these days I going to introduce you to a friend of mine that I know you will like. The other friend and I were talking and I said I had was meeting a friend at this store for dinner. the friend worked there. She asked the persons name because she also knew someone there and when I told her the friends first name she completed with the last name. It was amazing It turned out the first time I had met the friend I was having dinner with I was with the other friend years ago. It was so cool and still is. All three of us know we know each other and we all three respect each other. we don't talk about each other while spending time separately with each other. Talking about the person that is not there at the moment when two people of the three sided friendship are together is considered gossip that is usually done when one person has a fight with the other so reviels hurtful information to the person they have no fight with. Responding to that kind of thing usually ends up with the three sided friendship desolving and the two that had a problem with each other "make up" and continue eventually with the friendship. My suggestion. since this person seems to want to reviel info on another when the other is not around don't have contact with the person revieling information alone and also if that person revieling personal information on the other feels its ok to do this then she/he is probably revieling your personal information that you have disclosed to her/him in confidence which is all the more reason to not be in contact with this revieling of confidence friend alone.

As for the already revieled information - Think of it this way- when you talk to all your friends some friends you tell only a little bit to and others you tell alot to. And the information you tell is not told to each and every friend the same way. You tell them based on the type of conversation that is going on. It may nothing to do with how much you trust that person or you are lying or omitting information from and to your friends.

This reminds me kind of like the game where two people go in another room and one person does something. then both go back in the room, you sit in a cirlce and the one that watch the activity done whispers what that something was in a persons ear. They in turn whisper what they heard in the next persons ear and that person whispers it in the next ear. by the time it gets back to the starting point it is no longer what the first person had done because everyone interpretted what they heard differently and out of the context of what the situation was to begin with.

The information revieled may not be a lie just being taken out of context and twisted around to meet the needs of the person doing the revieling to you.

If this was me I would pass it off as - if this is true the person will tell me at some point when she/he is ready. Until then its just like the circle game and Im not going to get pulled into needless gossip or problems.
