I don't necessarily agree that Charlotte adapts herself to whomever she is dating, though when one is in a relationship (let alone a marriage) one does naturally become like the other. That's common sense, and is a component of a successful relationship imho, to have things "in common".
And on that note, of course Charlotte was "studying hard" when she was with Felix, they both were, because duh they both were going to school at that time. That's a given.
With Alex, she met him at at time she was transitioning from a young university schoolgirl to finding her own wings, which included living on her own, developing her interest in fashion, which she was immersed in since she was a mere babe, and that included attending fashion shows and also her boyfriend's art shows (being he was/is an art gallery owner). As to the other, I'm not surprised she was on covers, she's a beautiful young lady, etc. etc. etc. (this has been gone over ad infinitum
).
Continuing on the theme of Charlotte's interest in fashion (just like her mother before her btw), she furthered that interest & passion by starting her own
Ever Manifesto magazine (
Charlotte Casiraghi | BoF – The Business of Fashion ), with a focus on the environment (most likely influenced by her maternal uncle's own deep involvement in such). And then came the deal with Gucci, simultaneously with Charlotte getting back into the equestrian world, after she took a 5-year hiatus from it. This too ties into her interest with fashion, as well as horses, and journalism. On the contraire, Alex Dellal has nothing to do with those very interests of Charlotte (striking down the assumption that she adapts herself to her boyfriend, nope). This is why I'm not surprised they broke up; they're both going in two different directions. They met at a time when Charlotte was just starting out, finding out what she wanted to do, whereas her boyfriend had already found his niche in the art world. Five years later Charlotte is at a total different point in her life, which differs from her ex-boyfriend's, therefore they go their separate ways. Happens all the time.
With Gad, who knows what's next!?! But I doubt such a strong-willed young woman like Charlotte will be "adapting" herself to Gad. She's proven she's her own woman, and pursues her own passions & interests. Because of this I seriously doubt she will drop everything (i.e. fashion, horses, journalism, et al) to adapt herself to Gad. If anything, he will need to adapt himself to her, as her other boyfriends have done so in the past.
And for the record, Charlotte has always shown herself as a rather *discreet* private person, suing the paps before for their invasion of privacy. It hasn't begun with Gad.
The only difference is that her invasion of privacy has escalated since her relationship with this 40 yr. old French comedian/actor (btw he's a nobody in the USA; Charlotte at least is known here). No offense to Gad, just stating the facts.
On a last note, when Charlotte does eventually settle down and get married, she and her husband will need to have things in common in order to make the marriage work. That's when she & him will truly need to "adapt" themselves to each other. Jmho.
In the meantime, have a great time being young, in love with life, with nary a care in the world (except the paps, of course).
