Need some advice - Was I brave, what would you have done and did my actions have more impact?

No one deserves the kind of abuse you have tolerated. You are so much better off being rid of this man. I'm not sure why you went to his concert or why you're still looking for validation from him or his family. At the end of the day they're his family and they're always going to love him more then they love you. Who cares??? They deserve each other. Do you really care what a bunch of in-bread hicks are thinking? This family obviously has some pretty messed up dynamics if they're going to support him having a relationship with an obnoxious little retard. Be glad you're rid of these charity cases.
