At this time she isn't interested in romance with you, but it doesnt mean she isn't interested in you as a person or getting to know you. I see no harm in continuing keeping in touch with her, but allow the opportunity for the both of you to get to know eachother. I would let her get back to you though when she cancels out on a meeting or date instead of chasing after her. Don't do her work for her by chasing after and continuing to ask her to hang. She needs to do some chasing of her own as well.
