Okay, this is a really bizzare question. Krystie & Marty are my friends and Amy and David are my friends. My friend (Amy) had an affair with David. I am assuming that Marty & Amy know nothing about it. Now, Amy feels bad about it and the guy and her have agreed to not ever see each other again, however, now Krystie has made comments about things in her marriage not being so good. I don't know if she suspects something is going on or if something is really happening. Should I say something to Amy about it? Should I ask Krystie for more details? (I really don't want to get involved- but they are both my friends- and I don't know what to do). I don't really know what to do but, I hate to see two marriages fall apart and me stuck in the middle of it.
