It's hard to respect the privilege of friendship by remaining supportive while keeping objective and emotionally detached.
To listen is often the best support you can offer while those concerned find their own way through with the aid of having a supportive and confidential ear.
But of course that ship has sailed for now, and feelings will be pretty raw for a while as this new layer impacts the relationship dynamic concerning two couples and their allegiances to their own and one another.
Perhaps it's not all bad since it has instigated a more intense discussion which will resolve itself one way or another, but if there was one bone of contention from your determination, it would centre around your own sense of involvement as an 'affected' party:
- "It was hurting me so much having to keep this from her"
- "I was so angry that I told her the truth"
For that, it would be admirable to acknowledge to them that you may have overstepped (out of love for the friendship) and offer to smooth things over any way you can - some gesture to help bring everybody back into the fold again, recognising that relationships flow like rivers with many twists and turns to test the strongest of bonds.
If handled sensitively and without reservation, you should find a stronger friendship developing over time.
