Kristen Stewart has finally revealed as to what went wrong when she was in a highly publicised relationship with Robert Pattinson.

The American Ultra star has said that dating the 30-year-old actor was "gross" and "wasn't real life". It's not that I want to hide who I am or hide anything I'm doing in my life.

But considering I had so many eyes on me, I suddenly realized [my private life] affects a greater number of people than just me.

It was an opportunity to surrender a bit of what was mine, to make even one other person feel good about themselves."For Stewart, dating Pattinson yielded more attention than she ever wanted.

"I hated it that details of my life were being turned into a commodity and peddled around the world.

"If it didn't seem like a relevant topic, like something that needed help, I would have kept my life private forever.

But then I can't walk outside holding somebody's hand, as I'm followed everywhere," she says.
