I read an article in the guardian this morning that really moved me. It focuses in a woman's experience of online dating websites but also discusses the pain of divorce. She describes so well the initial pain and also the feelings that can keep coming back even after a few years.
It's been quite a few years since my exH left but every so often something triggers that feeling of loss, and every few months I still have a dream about him.
