Hey fish, you say you treated W like a queen and she spit in your face. Guess what, DBing is about finding an approach that works and often what we think should work e.g. Queen treatment doesn't! So you've basically hit a wall in your one and only strategy...that ain't Dbing, my friend. Next, you posted about your new friend "I also know that we absolutely would walk away as friends if the romance faded." I'll bet you thought your M was "absolutely" forever when you got married too, didn't you? Oops! It's your life fish but please live it wisely, the lady will wait for you if she's worth having. 'Nuff said. I wish you the best.
