I think this is a really individual choice. Going twice a week can be really helpful. I went 2-3/week with my longtime T for a while, and it helped me stay out of the hospital. I do think it can increase dependence, if you're worried about that. However, that doesn't always end badly. With longtime T, I was actually the one who initiated less frequent meetings (from once/week to every other week, don't remember how I decreased from multiple times per week, it was like a decade ago). So it's possible to become dependent and then move towards independence again without the pain that so many people experience. I wouldn't advise 3x/week unless you are DID - that's the only condition I can think of where someone might need that frequency and who wouldn't be better served by a higher level of care. Unless you're seeing a psychoanalyst, I guess, since my understanding is that they usually see clients at a high frequency.

I would consider several things before making a decision. First, what are your expectations in terms of how much faster you will get through therapy if you increase the frequency? What is your financial/insurance situation.?If you have a set number of visits, you need to make sure that they are distributed in such a way as to allow you weekly and biweekly visits as you approach the end of therapy. Going from 2x/week to nothing or 2x/week to a short period of weekly or biweekly before termination is not advisable. I would also want to know more about what your T's reasons are for increasing frequency, and what specifically she's trying to address by proposing this. It sounds like you feel things are going well, so I would want to understand what my T is trying to remedy by upping visits. My own reasons for seeing a T more than weekly have been related to my own instability or severity of symptoms, not to increase productivity, so I don't know how well that works. I have heard it said that you can't hurry therapy along because true and lasting change takes time. Just something to consider.
