My friend is losing her mind!!!?

Ok...My friend dated this boy for about 9 months then they broke up. She did her thing with 1 guy(whom she was dating at the time) and he did his thing with several women. Now when she goes to get back with the guy she had been dating for 9 months..he says no he cant be with her because she has been tainted with another man's touch??wtf?? So ne wayz she is now on this life long misson to get him back. He already has a new girlfriend but she still is pursuing him. Like even bringing the dude food and all. She gets online and writes these deranged notes.....like "I can't wait til the birth of our children and the day he becomes my husband. ill so happy." She says God has already set them together and she will just wait. I know he helped her get saved and become a better Christian and all but u dont have to dedicate your life to him... do that for God.She kinda sees me as the anti-Christ bcuz Im telling her she is losing her mind...but what do yall think? SERIOUSLY!
