How do you know if you have a codependent relationship with your therapist?

I think I’ve been seeing my therapist for about a year. He does med management so the sessions are typically about 15 to 30 minutes. I think the last time I saw him we talked for almost 2 hours. When we left everybody else had already gone home. We talk a lot about personal things too. Like I’ve learned a lot of things that he likes and we’ve shared suggestions for movies or books. I’ve learned that we have a lot in common and we are fairly close in age. I’m also really attracted to him. Which I know is a horrible thing for therapy, but I figured it didn’t matter since it was just meds, not really CCT.

Is this kind of relationship with your therapist normal?

He told me I have a personality disorder Last time I saw him. I talked to some friends of mine and they all disagreed with what he said. I’m wondering if maybe the relationship that we have is causing him to misdiagnose me.

So I guess my question is what’s the best way to let him know that I don’t think I can keep seeing him?

His birthday is coming up and I wanted to give him a book and just leave him a note in it. But, and I know this is unethical so I don’t want the textbook response, how would I approach may be telling him that I would want to keep in touch through email. I really like this person and I would feel really sad if I couldn’t talk to him. But I just don’t feel like we have a patient therapist relationship anymore. I’m also 100% dead set on at least asking him if we can talk through email or something I just don’t know the way to do it.

I know this is weird. Does anyone have any advice on this?
