I don't know if transference has stages [wouldn't be surprised], but just keep an eye on where the emotional attachment to your therapist could take you. I know this isn't what you're saying but I had a bit of a crush on a therapist once and pretty soon I was only going to the appointments so I could see her again - like a date, haha. But the whole thing was just pointless and I felt like I wasn't being honest with myself or with the therapist, and that never sits well with me. Counterproductive therapy-wise, imo. But still, maybe you yourself aren't heading down that path. All the best. Good luck.
