Without going into too many details, a friend confided in me that she has been having an affair. Our families are very close (emotionally and actually live nearby!), and she is one of my closest friends. The affair has been emotional in nature for a long time, but only recently physical. I am surprised by my incredible anger regarding this. I am mad for a variety of reasons, but as a result have found myself pulling away from her when I know she needs me to support her through navigating her actions in the past and going forward.

I guess I am just wondering if anyone has advice about this kind of situation--how to separate my emotional response to a situation I am not actually involved in, and how to support her moving forward, whatever that looks like.
