To put it another way, a therapist is not someone who will be sharing their lives with you in any significant way. They are there to teach you, support you, witness your struggle, help you do better. You are not there to do that for them.

It's different with friends, it's different with most other relationships, where you trade support and share fun and other things. Therapy is a different kind of trading, mostly money for help. That type of trading doesn't work out in the way you are hoping for/imagining.
