I'm sorry this relationship has been a disappointment to you. It's tough to have an interest in someone whose interest back is not really reciprocal. I think that's what it boils down to. What you'ld like to have is more than what she's really interested in. She seems to kind of give you mixed signals.

You mention helping her financially. That's being a really committed friend. In my own life, I've found that helping people in a material way doesn't go all that far in building up a bond. You mention that this lady doesn't have much money due to her daughter's dance class. People hard up for the basic necessities of life don't have money for dance classes. It sounds like the money from you wasn't so she could eat, but was for her to sustain luxury expenditures. You mention that you are afraid she "will keep on wanting more money." You're kind of hinting slightly that you feel there is an element of exploitation in this relationship. I get the impression that there is.

I think you are not wanting to call her because you don't see this being much of a friendship. I'ld say you might want to just go with that.
