I think it's hard when there's so many choices out there for therapy, how can you ever know there's not someone better for us out there? Is the grass going to be greener with an older woman? Or a non buddhist, or a CBT therapist versus and psychodynamic and all the colours in between.

But given your issues with interpersonal relationships it would be worth thinking what this is really about? Are you using the fear of attraction to not get close to him? Needing a new therapist as an excuse not to get attached or as away of avoiding investing in the therapeutic relationship? Or to avoid the uncomfortable feelings of being a loser in front of him? Are you repeating any pattern with him that you also have in your dissatisfying relationships in real life?

Just check your motives for moving on. Because if it's an of the things i've mentioned then you're just going to find yourself in the same position with any therapist.
