yes Speedy I have been in that position. I was upset when a friend chose to stay friends with someone that stabbed me in the back. The way I feel about it is, yes these two are friends, but if I saw a friend of mine treating another friend or anyone for that matter cruel, I would have to step back and think. Now if two friends simply did not get along for one reason or another that is different. But if I was the friend in the middle I may stay friends with both people. But I would never put myself out there for the cruel friend. In other words it would be a very casual relationship. If I had one at all. I usually taper off those type of relationships because if that person was so mean to someone, I may be next.
