So, OP, tell us the stuff you've told him you will and won't tolerate in a relationship. Oh, hang on, is he not that keen on anyone else being uncompromising about their needs?
Not entirely relevant to your case, OP, but your thread brought it to mind. I have a married male friend I used to be very close to we now live in different countries who often talked sentimentally about his first love, someone he met at university and was with for seven or eight years, who eventually left him, breaking his heart (and ended up married to a formerly high-profile politician, and was in the press a lot because of a major scandal, which was in no way her fault).
He liked to reminisce about her, her fiery beauty, her uniqueness, wit and charm, her brilliance, the intensity of their love, and to imply he would still drop everything if she crooked her little finger at him etc. (To which I used to say 'And your wife and two children?' And he would sigh and shake his head in a maddening 'Oh, you don't understand way' and I would change the subject.)
Anyway, the thing is, I've met her since I moved away, and as far as I can gather, the entire intense 'doomed young love' and her as Queen of Beauty and Uniqueness stuff is a figment of his imagination. She's a nice enough woman in a 'jolly hockey sticks and an Alice band' way, not a raving beauty and wit, and her memories of their relationship (I'd mentioned where I worked, and she knew he worked there, so it came up) are that it was a classic student 'starter' relationship for two teenagers from very sheltered, conservative backgrounds, and he was a gloomy, routine-bound loner who lolled about watching daytime TV and gaming while supposedly doing a PhD, and it was never going anywhere. And that he was a total commitment-phobe!
Meanwhile, he's in the process of divorcing his nice wife because it's 'no longer working for him', and still sighing over his lost love. (I have not shared any of my information with him.)
I suppose what I'm saying is that one person's Perfect Love and Heartbreak is the other half of the couple's mildly comic starter relationship.
