What should I say to stop her from doing this ? (details inside)

My crazy daughter, 40, is starting to call me every two weeks telling me her 50 year old boyfriend has no income and needs three thousand dollars! I’ve never met him, she barely works at best and I don’t need this. She hasn’t directly asked me for any money but I very much resent the implication. What short, to the point response can you come up with to make her realize she’s barking up the wrong tree and he’s not getting a dime from me? I have spent thousands of dollars on her for years and I’ve had it.
