Mm, I detect a note of resentment in your post, Pierre. Perhaps she wasn't as submissive as you would have liked? Perhaps she had the gall to turn down whatever offer you made?
On a more serious note, I agree that her breasts are not her best physical asset (though likening them to Cocker Spaniel ears is a tad uncharitable and overstates your case). But she has quite a pretty face, has superb legs and
une très belle croupe, il faut l'admettre.
As for her annoyingly high opinion of herself, I thought it might have occurred to you that that aspect of her personality could work in your favour, if you can manage to live with it. A woman with high self-esteem is:
(1) Far less likely to run off to see the plastic surgeon at the first suggestion from her boyfriend or agent that perhaps the body nature gave her is just not good enough and that perhaps she needs those horrid "bolt-ons" that so many East-European stars are now getting, following the U.S. fashion.
(2) Far less likely to jump at the first opportunity to go "travelling" to Vienna, Brussels, Frankfurt or Dubai in order to take advantage of her PSE because, as you well know, money is only part of that decision; the other big factor is self-respect, and this woman seems to have a good sense (perhaps even slightly inflated sense) of her self-worth.
I think you should persevere with her. Yes, it's going to be annoying for you (you're going to have to roll your eyes and mutter under your breath), but isn't your job similar, in a way, to an opera director dealing with a diva, or a Hollywood director putting up with an actress who thinks she's the next Marilyn Monroe? We, the paying fans, get to benefit from your hard work without having to put up with the annoyance of having to flatter and cajole these girls.
Anyway, DDF seem to think that Alyssia is worth investing in, so perhaps you should rethink your position? (By the way, I'd like to hear what DDF himself has to say about her, but he's not as generous with his time as you and Christoph are. It's a pity.)
Best regards,
