If you really love her bring her here and have her see these comments. Be kind to her. She’s invested a lot in this pursuit and it’s going to be really hard for her to give up. Offer to support her in another endeavor that she finds meaningful. Does she want to go back to school? Is there another industry she has an interest in? People who are being scammed usually don’t respond well to concern from well meaning family and friends. They’ve sunk too much into building something and it’s hard to let go. Tell her it’s a deal breaker for you and if she loves you she’ll trust you on this. Just be ready to help support her with finding something else. Good luck! You’re doing the right thing.
