The former couple, who raise two kids together, announced they were parting ways in June after 14 years together, reported Access Hollywood.
"I don't have the recipe for happiness, but I think the engine is simply having the desire. It's not feeling obliged or forced or repeating yourself. I hate, for example, whenever you hear someone say, 'You have work at being a couple'. No, you have to want to be there. And for me, I want to be right where I am right now," she said.
The actress, who is promoting her new film "Cornouaille", was initially hesitant to speak of her prior relationship with Depp.
"I don't want to talk about him. Who said that artists should sell their soul, expose everything about themselves? It's my duty to promote this movie, and my albums, but can you imagine what it feels like to see people making a business out of your pain," she added.
