breaking up is hard to do

I've spent 5 years with her, getting to know her. Being with her was a departure from the women I usually went with. She liked me for my brain, she was fierce about me to a degree I'd never experienced. The sex was strange - she was an ex catholic, and it always seemed to revolve around some kind of burlesque fantasy. All the time. I don't mind a bit of it, but there was quite a lot. She moved in with me. We spent two years in DIY stores doing up the flat. I asked her to marry me in front of 120 people. Her mother died. I broke my ankle and she nursed me back to health. I lost my job. She encouraged me to be self-employed. Sex dwindled and died to the point where my advances seemed to be rebuffed. She is hard and implacable and is not interested. I have become emasculated, dessicated, grumpy and frumpy. In the end, she just makes an arrangement for our end of relationship. We are now flatmates. And she wants the flat. We sleep in the bed but I crawl in at 5 after nonsense porn on the computer, and she gets up to go to work so we can minimise contact. And now the unknowing begins.
