I need songs for the following scenario?

I really like this girl and Ive talked to her for a while but i need something to get over the top. She loves music and Id like to play something for her on the piano. The thing is though that she is no ordinary girl. A couple years ago her boyfriend of a couple years died tragically. She was devastated and since really has had no smooth relationships. I want something, some song that "shows" her she can love again. I want to be there for her, Im just afraid, afraid to step over her bounderies and take her deceased boyfriends place because that isnt my intention. I want her to be happy. Help please?
