So I have a problem dealing with my two close friends, Kate and Josh. For over a year now we have had trust issues within this circle because there is alot of backstabbing going on. Josh is my best friend, and it has been that way for five years now. But I recently found out that Josh has been talking bad about me to Kate. (I found this out because Kate told me during an arguement we were having). When I asked Josh if it was true, he changed the subject by telling me that Kate talks bad about me! This isn't the first time something like this has happened though, it happens all the time. I am really tired of constantly worrying about what my friends are saying about me when they are together...what should I do?

P.S Both Josh and Kate talk bad about the other one when they are with me!
