i guess you have two options:

to accept things as they are
to try and change them

with respect to change that can be broken down into:

try and change her (i.e., try and tell her what you want)
try and change you (i.e., try and go with what she is doing)
leave her and find someone whos thinking on these things is the same as you

probably there are other options but... haven't had coffee yet ;-)

it doesn't sound like what you are wanting is unreasonable to me. as i said i would have been out of there a while ago. only... you know maybe i wouldn't have been because the guided imagery stuff does sound kinda cool. but yeah, i'm a process person myself as well...
