Why is my boyfriends ex who’s 10 years older than me saying derogatory things about him going after me for my age (I’m 26, he’s 38)?

She told me on fb that she told him that I’m closer in age to his daughter, who’s 19. She keeps saying things about how I’m too young for him to him. I also told her I’m not comfortable engaging about this more, respectfully, and she still sends me messages and won’t get the cue. Why is she doing this and why is she saying shit to him about our age difference?

She also said she’s shocked he took me to so many nice places so early on and that it’s not his M-O.
