What is my friend doing?

My friend started dating this guy long distance about a year and a half ago. She has changed dramatically while dating him. She has chased him to Florida and Texas and will basically fly wherever he summons her to. He NEVER comes out here to where she lives to visit her. They have no pictures on social media together. They are intimate but he won’t sleep in bed next to her for the entire night, claims he can’t because of his “religion”. But he can have sex with her? She is convinced she is going to marry this doctor. She keeps making claims about how she is moving out there soon and they will be engaged soon. There have been several occasions where a ring could have been presented and it wasn’t. I’ve met this guy exactly once and that’s it. Here’s the thing, I am actually engaged and have been for several years. She decided to just tell me she’s moving by the end of the year and they will get married in March 2024. How could she know that if they aren’t engaged? She was also supposed to move in July. Never happened. How do I tell this girl she’s wasting her time? I can’t even talk to her anymore because whenever she contacts me it’s about these fantasies. I miss my friend and would like to just talk about regular things with her but it always goes back to how she’s marrying this guy and moving so I make an excuse to cut the conversation short. I feel bad doing that but I don’t want to abruptly tell her the entire thing is crazy and hurt her feelings. What would you do and what do you think?
