A good friend of mine I've known for over a decade, whom I see almost every day, who supported me through some of my life's toughest times & I don't think I could have survived without her... and vice versa, opened up to me tonight about something apparently no one other than her has ever known about.
I promised her I wouldn't judge and that she could tell me anything.
Then she told me: during her divorce many years ago (her husband left her for someone else), her husband was out on a date with someone else & she felt so desperate she wanted him to come home to her. In order to get his attention, she told him their pet guinie pig had died (a lie). He agreed to come home.
So that he wouldn't discover the deception, she killed the pet. She was so ashamed she never told anyone.
How would / should one react?
