Everything is ephemeral in this world. Her temporary obsession with a new man does not mean it will last forever. Once she will have to delete all her pics and start posting cats. And I agree with @Darkhaven, scrolling social media will make you feel worse inevitably, you will see all those pictures with demonstratively happy and successful people and take it as truth. Every time I open Instagram, I feel depressed. You will never know what problems people face behind the scene, you will believe in what you see.
