My impression is that she is doing it because of the church connection? Sometimes, people extend themselves because another is in need, but that doesn't mean they can help. It could be that she realized she's not helping you, but feels an obligation (to herself, her beliefs, etc) not to leave you hanging or to reject you. It's possible to want to help someone and just not be good for that person. So, both of you are stuck in this situation that doesn't work, not wanting to hurt the other. Being thankful for her effort, and saying good-bye, can be a gift to you both.
