Maybe you don't need that level of attachment to new T. Maybe you're still comparing her to last T instead of accepting her for who she is. If you find this T helpful, maybe just let the relationship be what it is and let it develop naturally.

I didn't want to be attached to my T. I hoped that her being younger than me would prevent those feelings. Nope. I have had to just accept the relationship for what it is. It's still weird, but it is what it is. And my T knows about the attachment. She doesn't mind, and she doesn't treat me any different...except she tries to not be motherly with me so that I don't confuse myself more.

Besides, for those of us who are attached to our T's, our goal is to try to deal with our issues AND how to not be so attached. It might not be normal for you, but it might be healthier.
