I have brought it up with mine many many many many times. Mostly because when I start to feel any attachment, I freak out and pull away. Attachment feels dangerous for me. That being said, I have felt the same way as you. I think about her often and wish that she could be someone more in my life.

Bring it up, talk to her about it. T's are used to it and, if she has been practicing for very long at all she should know how to handle things.

Good luck!
