How do you help an older brother cope with a break-up? Yet I feel it too?

my brother and his girlfriend just broke up. but it isn't the its not me its you. its deeper than that. they had a talk and they found out certain things that might not be good for their futures. but they still love each other. I'm going to name them Josh and Amanda.I think from all of Amanda's boyfriends she loved Josh the most. And Josh loved Amanda the most. They were the closest and bestest of friends. and right know Amanda is somewhere crying, loving Josh, and Josh is feeling extremly upset. Josh tells his mom that she was the closest to her from previous girlfriends, and that Amanda even wanted to marry Josh. My Erika, loved Amanda like a sister! we were soo close in a way. im a child and she an adult. their in their 20's by the way, im still in school. I loved Amanda she was my big sister role model, we had good days and bad days together, and says we hated each other and were mean. But when I was said she used to always sayy awwww and patt my head, and I remember when she let me sleep on her shoulder during a ceromony, casue i was bored, and even was their to comfort my crying when i was sad. she was always a good person in some way, my mom in a way never liked her, but i knoew deep down she was a good person. and for the best Josh and Amanda broke up, still in love. And i loved Amanda as a sister, it feels like we will never see each other again, casue of the connection I had to her through my brother, when she visited and stayed her overnight. I even remember when I first met her. What can I do, my brother is sad, and I was crying on my own when i heard. how can i make him feel better when im so sad myself??How do you help an older brother cope with a break-up? Yet I feel it too?
Complicated situation, but life is all about change %26amp; adaptability. Your brother %26amp; you can only be there for each other, because I doubt that there are any magic words to make the pain of loss bearable. Time %26amp; each other's love is the only cure, I'm afraid. ~:|%26gt;
