After reading this, I came back to the start and thought maybe the word "died" instead of "plummeted" is what happened.
Everything done after is like taking shock paddles to the heart of the relationship.
So sorry that you both are plagued by the damage setup by our patriarchal society.
On the flip side a great karmic cold dish to say to him is this:
Since you only found me attractive when I was a "whore" instead of of as sexy madonna. I am moving to my apartment, where I can "whore" it up with others as much as I damn please.
Maybe then you would want to have sex with me in my apartment away from those madonna like house filled with porn women.
But the last four paragraphs is a lot of mean and hate from the anger monster within.
