Self-preservation and a need to recover from the loss of her boyfriend Stavros Niarchos to Paris Hilton are the reasons why Mary-Kate Olsen bolted from her studies at New York University and returned to Los Angeles, she says.

The 19-year-old mogul, in an interview with the fashion monthly W, acknowledges: “I miss him and I love him and I don’t speak with him anymore. It’s a hurtful and painful subject. This is a hard time for me.” As for Paris, she says, “we’re not talking.”

In going back to California, Olsen says, “I’m happy that I kind of realized that, okay, I just need to take care of myself right now. I need to be able to go to yoga and work out and just read scripts and go on auditions.”

The less-stressful life, she says, is “what makes me happy. You know? Like, (school) papers don’t really make me happy.”

In mid-October it was announced that Olsen was beginning an approved leave of absence from NYU “to focus on her increasing responsibilities as co-president of Dualstar Entertainment Group and to pursue personal interests,” said her rep, Michael Pagnotta. (Olsen shares responsibilities at the company with her twin sister, Ashley.)

When asked if leaving NYU had anything to do with Mary-Kate’s health, Pagnotta said, “No, it doesn’t, and this is the most important thing. She’s not reentering any kind of treatment facility or anything like that.”

The summer before classes began, Mary-Kate checked into the Cirque Lodge rehab facility in Sundance, Utah, for treatment of an eating disorder. During her first semester, she continued her after-care treatment with access to two teams of therapists, nutritionists and eating coaches in L.A. and New York, PEOPLE reported at the time.

Mary-Kate and Ashley began attending NYU in September 2004.
