She has always strived to balance her royal duties with her desire for independence, making her a prominent figure in the Swedish monarchy. A pivotal moment in her life came in 2018 when she moved to Miami, Florida with her husband, Christopher O'Neal, and their three children. This choice has caused much discussion, as many see it as a quest for a more peaceful life away from royal duties. Living abroad, she has strived to balance her royal responsibilities while remaining a devoted mother and wife.

In interviews, she has stressed the importance of combining royal ties with her own aspirations to shape her life on her own terms. Before meeting Christopher O'Neal, Meline had experienced personal challenges, including a long-term relationship with lawyer Jonas Burkstrom that began in 2002 but ultimately ended without marriage. Despite the emotional damage, she found happiness again with Christopher, whom she married in 2013.

Their wedding at the Stockholm Royal Palace attracted considerable public attention, marking a notable event for the Swedish monarchy. Christopher O'Neal, a successful businessman with dual British and American citizenship, made the unconventional choice to renounce his royal title to focus on his career. The decision sparked much conversation, as this rarely happens in royal marriages. He emphasized the importance of privacy in the family and often discussed the difficulties associated with public scrutiny.

When discussing their life together, Christopher noted that being married to Meline came with its challenges, but he always expressed his deep and unconditional love for her. Princess Meline has sometimes faced discussions about her involvement in royal affairs. While some have argued that she should be more visible, many understand her choice to live a private life in Miami, recognizing everyone's right to privacy. In 2019, King Carl Gustaf changed the way state funds are distributed, affecting his grandchildren, including Meline's children.

Meline responded positively, claiming that this would give her children more freedom to choose their own paths. While the move to Florida was initially seen as an escape, it also brought its own challenges, such as being away from family. However, Meline and Christopher maintained close family ties despite the distance. In the summer of 2024, the family unexpectedly returned to Sweden, reigniting interest in the royal family. The move could signal a return to royal duties for Meline, although her role remains unclear.

The Swedish Royal Court has confirmed that she will continue to serve as vice-president of the children's charity founded by her mother. Her recent attendance at the opening of parliament created excitement, underscoring her re-emergence. Meanwhile, Crown Princess Victoria has resumed military training and Princess Sophia announced her fourth pregnancy, putting Meline in the spotlight as a potential active representative of the family. Although the family has returned to Sweden.

Christopher continues to prefer privacy over public life, highlighting the challenges faced by outsiders in royal circles. Their future roles within the royal family remain a matter of curiosity. The family’s return to Stockholm could signal a new chapter in their lives. It would give Meline the opportunity to become more involved in royal duties she once hesitated to undertake, while also allowing her to reconnect with loved ones and find a new balance between her personal life and royal duties.
