Lenny expressed it well, your experience is unique but we've all been in your place I think. I do not mean to belittle your pain, but you will get over it. Not today, not tomorrow it may even take years to be able to look back at this relationship without feeling a single bit of pain. But I promise you it will come.

When I look back at my own expience, I remember the anguish I lived with, but to be honest I don't remember why. When I look back now I see a man that was not worthy of my love. Please realize that in the future you'll see this man and his faults and realize you're better off without him. You needed to experience this to appreciate the joy that you will have in the future.

I'm so sorry that you're feeling this way now. A change might do yourself some good.
