T's can't help one forever. It's a marriage of sorts and since it's about the client they can mature in ways or directions that aren't something the therapist is "good" at. Occasionally mine would suggest different someone's she knew who specialized in certain aspects of what I was interested in, directions I appeared to want to go she could have me go see, see if they were of more help to me. I always declined; I knew what my T was good at and that's what I wanted to learn/emulate and was perfectly happy to "practice" getting better at it with her.

Everyone has different backgrounds, interests, attributes, and skills. It's quite possible no one person can take you everywhere you decide you want to go.
