This girl was dating my moms friends son. (By default hes my friend.) She posted something on the school story and I thought she said the n word so i added her and she added me. Fast forward her and my friend break up. They where only together for ONE MONTH. And that was a month or two ago. She I super funny and kind. BUT all she talks about sometimes is my friend. Shes obviously obsessed with him. She tried to move on but cant. My friend literally has a girlfriend now. And shes literally still caught up with my friend. I never met her irl. Should I just tell her if she talks about him again ima block her
