Father tells daughter to stay out of his personal life, asks her to stay with her mom

Divorce can be difficult for children to navigate, especially when it comes to their parent's dating life. Shea, a 16-year-old girl, is struggling to accept that her father is moving on with his life. Initially, Shea was supportive of her father's decision to date, but things changed when Shea found out that her parents had spent the night together. Shea has since been interfering with her father's dating life, even going as far as to sabotage his relationships. Despite her father's efforts to explain the situation to her, Shea continues to send him pictures of her mother and updates on her fitness journey. The situation came to a head when Shea refused to let her father's girlfriend into their home. In frustration, her father suggested that it might be best if Shea stayed with her mother until she could come to terms with his dating life. This has caused tension between him and his ex-wife, who thinks he's being an 'a**hole'. Despite the difficulties, it's important for Shea's father to prioritize his own happiness and well-being, while also being sensitive to Shea's feelings. How can he navigate this tricky situation without causing further harm to his relationship with his daughter?
