It doesn't automatically mean she will need to terminate you. It's also something that you could potentially work through. Even if she's feeling countertransference issues, that's something she could potentially work through in supervision or consultation.
Have you shared anything about attraction with her before? In my experience, if you try to just ignore the feelings rather than talk about them, it can make them more intense.
You don't need to share all your feelings at once or the intensity of them. And you could just ask her thoughts on transference in general. Even just, "Hey, I was reading this thing on a forum about transference and was wondering your thoughts on it." Sort of touch on the topic, see how she reacts.
