George Weasley
After the death of his twin, George retreated into Bill's old bedroom at the Burrow here he spent several days refusing any company but his mother and his sister, though they didn't get much out of him except a quiet tolerance for their presence. Everyone else got things thrown at them. As time went on, he slowly returned to the land of the living, though he didn't speak for a fortnight.
He had his twin cremated and put into a dazzling purple urn that lives on his mantle because he can't bear to be really separated. He did not go back to his flat above the shop, he instead bought a house in Hogsmeade and opened a second WWW location and hired a manager to run the original one, which he hardly ever visits unless he has to.
Not long after he finally moved out on his own, he and Angelina started hooking up. He knew it was wrong for both of them. He knew that she probably turned to him because he was the closest person in the world to Fred, but it gave him someone to be comforted by. Yes, she was his brother's ex, and yes she probably imagined somewhere in the back of her mind that he was Fred, but he didn't care.
When she got pregnant, he married her, because that's what you're supposed to do. And he loves his kid so stinking much. His kid is the greatest. So great they made another one, which isn't quite done cooking yet.
George doesn't love Angelina, not like he still quietly loves Alicia, but she is his best friend in the world that he gets to sleep with. He adores her and is loyal and committed to her and they're a great team for their kid(s). He's content with his life, after a fashion, but he still misses his brother every single minute.
