Why would J.K. Rowling end the 7th book the way she did?

 She made Harry and Ginny marry, makes sense. Ron and Hermione marry, also makes sense. I want to know what happened to Cho, George, Fred's body, (they don't mention a funeral) And the other Weaslys and Hogwartians. And how about the Death Eaters. Shouldn't they just kill them? SHE DIDN'T EXPLAIN ANYTHING!!!  >:( ??? >:( ??? >:(

Well. J.K.R wanted to end the series with a 7th book. She couldn't fit much for information in the 7th book, so she ended it with the epilogue. I think she wanted everyone to imagine for themselves what happened after everything that went on.
But I get what you're saying. I wanted to know what happened to everyone.
Maybe Cho died in a fiery pit of death.
George DID marry Angelina though. Had 2 kids.
Obviously Ginny married Harry and Ron with Hermione like you said.
Percy married someone named Audrey. Had 2 kids.
Charlie Didn't get married.
Bill and Fleur Had 3 kids.
