Is what you're getting out of texting really worth that kind of money or Is there another way you can get support? if not i guess i might suggest only you initiate the texts if absolutely necessary. I'm not trying to be critical, but her initiating and then charging so much doesn't sit well with me either. What if you didn't respond- would she still charge? Maybe an extra session when you can fit it would be more realistic in terms of the cost involved.
