Hmm, it depends how he'll use their experiences for his shows etc.. If it is in the sarcastic -wanna be funny- way he mostly uses, I would not like it in her place.
I remember that in the beginning, even with Alex Dellal Charlotte seemed more in love than he with her. But then their relationship has been well for enough years.
Gad is an older guy, he already had a son and he has already gained some perceptions for life, that a 28 year old girl cannot change them. They did not gain any experience together, he has been to her age and "knows" some more things about life. For Charlotte this was the beginning. Nevertheless, it is different having a relationship with a man of the same age as you and with an older man, i guess. There can be positives (e.g. learn from him) as well as negatives in such a relationship. For example, the needs and wants you have from life do not keep up with one another's.
