Bumbling - You know inside what you need from a therapist. Have you told this guy what you need?
If you want to look for another one, you will have the same issues unless you screen for what you want.
Much like getting a plumber or electrician or doctor, do you go with the first one you call? Sure, when it's the first time.. You have the professional work on something (fix toilet, add outdoor light, take care of stomach bug, whatever) and you think... I didn't like that. And you call another one.
And now you have more experience. So you have questions to start out. Whose fault is the affair? (if the answer is "the marriage was not meeting your needs", RUN) Will you ask me tough questions? (yes) Do you have emergency hours? (if this is important) etc., etc.
This is very important. You are spending a LOT of time and money and your emotional health is at stake. It's worth telling your story five or six or seven times to get the right therapist.
