The second part is talking much more about grieving an abusive relationship than it is about the unfairness of your situation (which I also know).
In both situations, there is grief but its kind is different. Mine is too painful, but that was the price I decided to pay with “radical acceptance". I will share the story at some point…
And even in such circumstances, I decide to keep the love and affection I have in my heart for the person. That’s a choice I am able to make today. The former me before the out-of-body experience would not have been able to forgive, needless to mention love.
That’s why I’m always feeling beyond grateful for anything extremely hard the Universe has been throwing at me. It has always happened when I was ready to handle it!
