Big dilemma (maybe a trigger?)

I have a friend from my other online forum (for SO's of depressed people) who just had her heart broken and is talking suicide. She lives 3000 miles away so I can't do a whole lot from here except phone and email (and I'm actually kind of nervous about giving her my phone number, so I haven't done so yet).

Some facts:
- she's 56 years old
- former Woodstock hippie and band groupie
- had sex with a rock star when she was 18
- "loved him with all her heart" for the next 30 years
- reunited with him, somehow, 2 years ago
- he lives in another region, so when he visits her city, he always stays with her
- he has never kissed or had sex with her since reuniting
- he has never promised her anything more than friends
- she has been talking for 2 years how she is going to talk him into marrying her so that he can continue his music and she will support him
- and now, she has learned that he has a new girlfriend and while he has been kind to her since then, he's getting really uncomfortable because she is so devastated and distraught over it

My dilemma is that she talks suicide in once sentence, because "there is no one left to trust" (which, I think we all can agree that she invented the relationship to begin with as he doesn't seem to have led her on, from her account). Yet in the next sentence, she goes on to say how she needs to make him "see the light" and "open his eyes" and "he just has a fear of commitment". I know that it's hard to accept rejection, but she's still entertaining fantasies of them forming a romantic relationship.

My fear is that she is obsessed and fixated on him, Glenn Close-style. If she can't have him, nobody will. That kind of thing. She won't seek medical attention on her own (she had been locked up in a psych ward in the past and don't want to risk it happening again) and isn't interested in trying medication. I am thinking about sending her a gift certificate to some yoga classes to hopefully get her to relax and clear her mind a little.

I looked through the Resource Directory and Disorders sections of the PC site and she doesn't fit OCD, although she does seem obsessed and fixated on this rock star dude. Classic groupie. Does anyone know what I can do to research ways to help her? I can't even think of any good keywords to Google.

Thanks all,
