So was wondering what you would do. I was walking up to school and one of the mums was talking to me and it had been bugging me where I know her from. So I asked she then said she works for the police and it hit me that she had helped with a problem I was having with my ex. She was so kind at the time she really helped me. I was shocked to realise who she was and so just said oh thank you, you helped with a ex and kind of bumbled on until I got away. She did say she doesn't remember me which I hope is true and not her being polite, but now I'm wondering if I should ask her not to say anything to anyone or just keep my mouth shut.
