I've read some of your back posts and I really feel for you. This sounds really painful and I'm sorry it happened.

Of course this is your decision completely. However, you did ask for advice so I'll give you my opinion. I think that you should transfer to the male therapist that your primary therapist suggested for the purpose of dealing with this attachment. I think that this option might hurt more in the beginning, but I think that the second option (of trying to work it out with her) will hurt longer.

I think that it is very nice that she is willing to email you during that time and that she will see you again when you are ready to work with her. Maybe remembering that you aren't saying goodbye forever will help. But I do think getting some distance from her might help you work through it more quickly.

I also think that the fact that even though you are hurting so much, you are still able to empathize with her uncomfortableness says something pretty awesome about you. I don't think that you should take her pain into account in your decision making. Therapy is a place where you are supposed to be selfish and do what is best for you. However, I think that you being able to feel for her is pretty good evidence that someone will be very lucky to get to be with you someday.
