Same here, except for when the fantasy became real life.
We would go to the grave of her movie star ex to lay flowers on his birthday. He died from an overdose but apparently tried to call her as he was dying, only she didn't pick up the phone because she was mad at him.
The father of her eldest daughter ran away in the middle of the night and has never been in contact since. However, later found out he told her she was broken and incapable of love (guess he figured out the BPD and definitely went no contact)
Then there was me, she decided overnight she wanted a divorce because we loved each other so much and like Richard Burton and Liz Taylor, if it's meant to be, we will find each other again in the future.
Only when I brought her back down to reality, that story changed to that I ran off in the middle of the night, leaving her and the children struggling and alone (I guess she didn't have time to think so she went with a story she already knew). She was livid that I flew to New York instead of back to the UK because it screwed up her fantasy and control. She made up false allegations to the police that I'm somehow going to turn up and steal the kids from her.
I think the funniest (and I can laugh at it now) was when I took her out for a romantic meal in December. In the middle of a full restaurant, she burst into tears as though I had just ended the relationship and created such a scene without anything being said or done to provoke it. The most embarrassing part was the free desert and free meal we got as a result of it because the staff had no idea what was going on and neither did I. However, the looks I got from the other customers, you would have thought I had just ended the marriage.
