That just sounds like liking your therapist. I like my therapist in rational ways, and I idealise him too.
Example of rational ways I like him: I think he's a really good therapist, I respect him, I think we are a great team and he is a good therapist for me.
Examples of idealisation: I sometimes feel like he is perfect, infallible, I read things he has written like they were written by a genius. I imagine he is a perfect husband, father, friend, lover. Etc.
For me that's the difference. And actually I think the idealisation is the cause of many ruptures, because I expect sooo much of him, and I am very disappointed and hurt when he can't fulfill my idealised expectations.
