Settle a debate

My friend and I are debating on N behavior....I think her BF is N as many parallels with her BF and my exN. N or not, he is treating her like crap. He told her not to contact him anymore. She contact him few times. He doesn't seem interested in connecting with her. He isn't one to Hoover, so I said if she ignores him he WON'T contact her. She thinks if she ignores him he will contact her, so she told him not to contact her anymore bc she she knows he never cared, thinking it will make him panic and then contact her. Although in past he never hoovered, and it was her giving in by contacting him that reconnected them, she is waiting by the phone for his call, she is waiting for 2 weeks now. She gets very angry when I talk about my exN and NPD and possibility her BF is N. I am trying to help her move on. I see the damage it is doing to her. She denies that what she is going thru is same as what I went thru with exN. She does think that bc i blocked my exN and he hoovered me, that her BF will do same. Any thoughts or advice I can give her would be appreciated, especially thoughts on if he may contact her or not. Thanks
