Hilary Duff unsure if marriage works

Hilary Duff in't sure she believes in the concept of marriage any more since she filed for divorce from her husband Mike Comrie.

The 27-year-old star and retired hockey player amicably separated in January 2014 and Hilary eventually filed for divorce in February 2015.

Since the end of her seven-year relationship with Mike - who she married in August 2010 - the 'Wake Up' singer has been questioning whether committing to one person for life is something that people should do.

Speaking in the April 2015 issue of Cosmopolitan magazine, she said: "I don't want to sound bitter because I'm definitely not, 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."

Hilary says her and Mike's relationship failed because it stopped working as they just grew apart and weren't as in love as they were when they first got together.

The 'Younger' star - who has two-year-old son Luca with Mike - said: "Mike and I were very in love when we met. We both really wanted to get married. I'd been working since the age of 11 or 12, so making that choice at a young age seemed right for me. Maybe it wasn't, but we spent the majority of our time together really happy. 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. I'm lucky for the person he is and I am and how we decided to handle this."
