That is the hardest part, I think. Reconciling, in our minds and hearts the person we once knew and the person that "is" now. Especially when it turned on a dime, literally overnight.
And, it's not a civil parting...the coldness, everything is so hard to bear, b.c it's so unnecessary.
I'm sorry that you have so much on your plate now. And on top of that, an H that is acting like an alien.
