My Step-DD has had a text from her real Mum - who was abusive towards her for 16 years, demanding her A-level results and PROOF of acceptance into a university, or she will stop paying her any money at all. She doesn't offer her a large about of money in any way, yet as a student obviously all money helps.
However, her demands seem odd, and understandably DD would like to avoid any communication with her, especially as we don't really understand why she's made such a demand?
What would you all advise?
