You have kids, right? Wasn't there a point when they were growing up (or a number of points) where you had to step back and let them find their own way? I bet you didn't want them to separate from you, but you did want them to be able to do things on their own. I think that is the position your therapist finds herself in.

I also think the parent - or the therapist - who can let their children/client go when it is time for them to do so really, truly cares about them.
