"My topic is love. It always has been," the singer said.
"It's my motivation. It's what I think about. That's who I am at the essence. But what I thought about love for my first nine albums is very different from what I think about it now, after everything I've been through", she added.
After three divorces, Jennifer had confessed she was in no rush to walk down the aisle again, and when her and Caspar first began to date in 2011 it was "not meant to turn into anything more."
"In the past, love for me has always meant forever, and sure you nurse those fantasies, but I don't try to force it anymore," she said in an interview with InStyle.
"I hung on to my fairy tale ideals for a long time. But where I am now, what I've been through, there are no rules. There are lots of ways it can turn out instead of just one."
