Another thing is, how will she be treated within the Muslim community? They hate Jews. Even if she gave up her Judaism, she's still of Jewish descent and I don't see how the Muslims will completely overlook that. She'll never really be a part of their community in the same way an Arab would be.
I'm afraid that she's going to end up facing a lot of abuse later. I hope not, but still... Maybe if that does happen though she'll come to her senses.
