Let her decide what to do on the insurance end. Some therapists and pdocs really struggle with insurance companies and their reimbursement/loops to jump through, etc. It sounds like maybe she's thinking she'd rather have you pay on a sliding scale than have to messing with the insurance crud now that she's thinking about it. That's not a comment on you or on her wanting to work with you. She's just perhaps preferring the idea of the sliding scale to the insurance set-up. Try not to make this about more than a business decision for her. Sounds like she's just done some thinking beyond your session about this, not that she wasn't honest with you in your session. Just that she's continued to consider the situation.
