The thing with boilerplate therapist talk is that it doesn’t mean they’re not using it to express a genuine emotion. (Technically the phrase “I love you” is also boilerplate human talk.)

I’ve heard the “I genuinely care about you” from two different therapists. One very quickly showed that it was a boilerplate comment for her, the other demonstrated repeatedly that for her it was genuine, if expressed formulaically. (Of course, she’s the one I’m mad at right now.)

So you know your therapist and you can judge whether he’s sincere or not. If you’ve seen nothing to indicate otherwise, don’t let the opinions of us random strangers on the internet decide for you.
