STOP LOOKING. TELL YOUR SO-CALLED FRIENDS THAT YOU DO NOT WANT TO HEAR IT.
Why are you torturing yourself in this manner? How does it help you to know any of it?
Why are you still asking what to do? You know the answers! Don't look. Don't listen. Don't contact.
I am not trying to be mean. I just want you to see that all you can control is you. It doesn't matter what she is doing or why. You have no control over that.
You know what you should (or in this case, shouldn't) do.
