Grief is a funny thing. I mean peculiar, not ha ha funny. Its really very universal, I think. If you were to substitute my work for your ex in your first post, it will read EXACTLY the same for me. I left a career dozens of years in the making last November. It was my dream job and the roughest decision I have had to make in quite some time. Had it not been a matter of ethics, I would still be there. It could not be more complicated, misunderstood by others or controversial than if I quit being a nun and its compounded by how I am known all over the county, like it or not. So I am often pressed to explain this when I don't even want to talk about it. The first two months I hid in my house. Emotionally I am about where you are. I look better now but don't scratch the surface. Life alterating, deeply felt experiences take time to process. I won't be myself again for a year or better. You are absolutely right that it's a "two steps forward, one step back" process. Grief makes us fragile so go easy on yourself. Be vigilant for remenants of bitterness and eject those asap. And learn something valuable out of it, about you, about women, to help offset the pain. For someone who has sustained a great loss, you are fine and will be even finer too. So will I.
