I don't think she was sent to ask you, I think it was just repeating. But, it might be a reason to reach out, especially if it is bothering you. Give her a call and mention that her daughter said something about you not talking to her. Let her know that you hadn't heard back from her, but would be happy to hang out again with the girls, or something to that point. It doesn't have to be confrontational, just let her know that you thought she seemed to busy, but enjoyed spending time with her. Then it is her move. If nothing happens, then oh, well.
