Ambivalence about therapy has been a frequent theme within therapy for me--I often feel guilty about going, or like it's self-indulgent, or like it's selfish to take time away from my work responsibilities to go to therapy. Or like there's something wrong with my seeking help or relying on my therapist in any way. I suspect that he's right that going more often will bring those up even more (it has in the past to a certain extent). So I don't think it was a general statement about increased session frequency heightening ambivalence, just an observation that he expects this particular theme and issue to intensify for me as therapy gets more intense.
