Nina Dobrev, Austin Stowell split after 7 months of dating
The couple parted ways because they both are too busy to see each other, reported People magazine.
"It started to get hard with both of their schedules. They remain on good terms," a source said.
Dobrev was spotted spending time without Stowell, both at the Super Bowl and on Valentine's Day.
Before Stowell, Dobrev was in a long-term relationship with her "Vampire Diaries" co-star Ian Somerhalder.
The couple split in 2013 and he went on to marry "Twilight" actress Nikki Reed last year.
