Gert van der Graaf, 37, was arrested by police on the Swedish island of Ekeroe where the former pop star had a home, police said on Monday.
Mr van der Graaf had been the singer's boyfriend from 1997 to 1999, but had been issued a restraining order barring him from seeing or talking to her in 2000.
He was also deported to the Netherlands, his home country.
He returned to Sweden earlier in the year and was arrested by police after neighbours saw him near the Abba star's home.
"I love her still. I will never forget," newspaper Expressen quoted him as saying on Monday.
Ms Faeltskog, 53, was one of the biggest pop stars of the 1970s with the Swedish four-piece Abba.
Catapulted to fame after winning the 1974 Eurovision final with their song Waterloo, they scored a string on number one hits all over the world.
Ms Faeltskog was previously married to fellow band member Bjoern Ulvaeus. The couple had two children, but divorced in 1978.
For the last decade, Ms Faeltskog has led a reclusive life, devoting her time to yoga and astrology.
