"Wants to meet him" indicates that she is not in love with him. She senses the massive delusion that he's hiding under, she knows that the Zack persona he's presenting is not the real Cloud. You don't love someone you don't know.
She's interested in the real Cloud, sure, but what sort of interest? I don't think it's romantic, because the real Cloud is a mystery to her. Part of her is just the friendly, nice, outgoing person she is, but I think most of her feelings are more motherly. She's worried about the poor child with the skinned knee (or, in this case, the shattered mind).
