okay, this might sound like some weird advice but bear with me...
the next time you two talk about this, make sure it's
in person. IM is great for flirting or small talk, but for serious things like this, there's no substitute for face-to-face interaction.
when she says something, really listen to her empathically, think about what she's really trying to say, then repeat it back to her. for example:
Her:
i think i want a therapist
You:
you want to get a therapist.
or...
Her:
i might just kinda think about things on my own
You:
you just want to think about everything on your own for a while.
i know that seems odd, but it does two important things... A) it shows her that you're really listening to her, but
aren't judging her or telling her what to do... and B) it gives her a chance to hear what she's just said again, causing her to think about it more closely... "is getting a therapist what i really want? no... that doesn't sound like the right idea." or "hmm, well i have been thinking about things on my own for a while already... maybe it's time to get someone else's opinion."
hopefully you'll find that she'll open up to you a lot more because you're not being pushy, yet you are helping her through her problems... eventhough she is really doing all the work.
good luck.
