Feelings for therapist

I have feelings for my therapist. After our session a few days ago, I realized that I cared about him. I see him twice a week and he’s okay with me coming in without an appointment if I’m distressed. I know it’s his job to care about me, so that’s why I’m conflicted about how to act about this. Can people with some experience with this give some advice?

Edit: I don’t know if you guys will see this, but I brought it up in our most recent session. I told him that I would transfer therapists if he was uncomfortable, but he said he wanted to help me understand this. I’m so glad I told him because what he said about it made so much sense to me.
