What does she like to do? Is she into home shows or other interests? Maybe if something like that comes up, you can ask her if she'd like to go somewhere that would really interest her, even though you weren't really into it. It would show that you're interested in things she likes.
I think you're on the right track but it will take time. Just continue to be there for her. I know it's tough but it will have its rewards eventually.
