When I saw this episode when I got my DVD sets, I got the impression that Lois was telling herself not to fall for him as much as she was telling Clark not to fall for her. It would be consistent with her character that she knew she lacked trust and love in her life, but had convinced herself that she didn't need it and wasn't going to spend the necessary time learning to trust and love any man. It makes Clark's long campaign to burrow through her walls more poignant and ultimately worthwhile to both of them. Makes for good romantic drama, too.
Any thoughts?
