RunningInRain, I have followed your story and I am wowed.
20 years ago, my partner ended our three year relationship but forgot to tell me, he simply left. I followed him around, I begged, I pleaded, I cried my eyes out but he just ignored me.
A few months later I was reading, having a cup of tea and I saw him enter the cafe with a girl. She went to use the toilet. He came over and I cried and cried. He said something along the lines of: "I hope you get better soon". He stood up and left when the girl came out of the loo.
Soon after I found a whole box of diazepam down the street -I swear- and I figured it must be a message from the universe telling I'd better take myself out of the equation. I went home, wrote him a ridiculous letter, took all the tablets and hoped I'd never wake up. Except my sister, who had a key to my flat, happened to come in unexpectedly in the small hours after a night out in the town and found me. It took me many, many, many years to get better.
My life carried on, I travelled, had many lovers, got a career, a house, a man I admire and a child. A few years ago I even had the "satisfaction" of him contacting me via facebook to say that ending our relationship was the worst mistake of his life and that he had never had a bond as meaningful as ours again.
When he contacted me, I hinted at the fact that I had had a really bad time when he left me but an apology never came, he just minimised my feelings. I look back on that whole mortifying, undignified period and I am, to this day, so very ashamed.
If I could turn back time, I would do exactly what you did. I know it is hard now but you will look back and you will be very proud of yourself. Good for you!
