Hilary Duff
A second marriage might not be in the future for Hilary Duff after her divorce from Mike Comrie. Cosmopolitan

Hilary Duff has broken her silence after filing for divorce from Mike Comrie last month. The two were married for four years, but the former Disney star told Cosmopolitan magazine, in its April issue, that they drifted apart. She also wondered: Is any couple meant to be together forever?

"It wasn't working well enough to stay together, but there was still a lot of love involved. It was just a slow set-in of us not being the match that we used to be,” Duff, 27, told the magazine, according to Us Weekly. "I'm lucky for the person he is and I am and how we decided to handle this."

The singer and actress filed for divorce Feb. 20 after a yearlong separation. She cited irreconcilable differences and is seeking primary custody of their son, Luca, who will turn 3 next month.

Duff seems to have no regrets about getting married at a young age. Even though she acknowledged it might not have been the best idea, she thought it was the right choice at the time since she had been working since age 11.

Now that her marriage is on its way to being officially and legally over, Duff mused that another marriage might not be in her plans. "I don't want to sound bitter because I'm definitely not," she said. "But I don't know if people are meant to be together forever. Things happen over a long relationship that you can't always fight. A marriage of 20 years, the accomplishment of that must feel really great, but there are also huge sacrifices. I just always want to fight for happiness."

Duff seems to be proud of her cover shoot with the famed magazine and posted several pictures to her Instagram and Twitter accounts. “Ya made me in pretty in PINK…” she wrote to photographer Eric Ray Davidson in one of her posts.

Since she’s not with her husband anymore, does this mean she’ll have a chance with long-lost love Aaron Carter? The former teen heartthrob tried to woo his ex, whom he cheated on with Lindsay Lohan in the early 2000s, by sending out advances on social media. Apparently, it wasn’t the best choice. "Him reaching out through social media? It's ridiculous!" Duff told Cosmopolitan. "But then people do it all the time, like Chris Brown and Karrueche? Come on, guys. Keep it between text messages."

Comrie, 34, doesn’t have much of a chance either. He got drunk and tried to pick up a waitress at a Los Angeles steakhouse, a source told Us Weekly. When that didn’t work, he tried to pay her for sex. This incident was the final straw for Duff and led her to file papers. “He totally blew it,” the source told Us Weekly.
