I'm close with my brothers partner and so is my daughter. He's leaving her and I will not be able to have a relationship with her after this. I'm very supportive of my brother and CANNOT talk to him about this. I feel devastated and like I'm going through a breakup myself, as daft as that sounds. I wish we weren't so close. How do I deal with this? I'm going to really miss her. Do I sound really selfish here?
