None of my friends could stand her. They saw the way she treated me, and were offended on my behalf.
Which only made me distant from them. Little by little I withdrew from them all, so that in time she became my only source of emotional contact. Once she was no longer part of my life I had no-one to turn to.

You can rehearse the history of how it came to this. Ultimately it was simply the wrong thing.
