Duff wonders if ' together forever' exists

After filing for a divorce from Mike Comrie, actress Hilary Duff says she has no idea if people are meant to stay "together forever".

The 27-year-old shared her views on love and relationships while talking to Cosmopolitan, reports mirror.co.uk.

"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," Duff said.

The former couple separated in January 2014 almost four years after they got married. She filed for divorce last month.

The actress and singer also said that they were "really happy" throughout most of their relationship before they simply started to drift apart.

She 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."
