In all honesty here, what you need to learn is how to pay attention to the entire experience in how this therapist sat, listened to you, and gave you permission to share and how that helped you feel connected to her. This whole interaction is SO IMPORTANT to view and learn from because YOU CAN LEARN HOW TO DO THIS YOURSELF when YOU are establishing a relationship, actually any relationship.
It is actually a skill that you can LEARN and is what many therapists learn themselves, but you don't have to be a therapist, you can just be a better person overall and be able to learn HOW TO SHARE AND LISTEN TO OTHERS better.

A lot of men don't learn this and get married and down the road the wife becomes unhappy somehow. And by the time they get help with a therapist, that time that a real bond should have been formed has passed and often the repair fails. It is sad when this happens and all it means is that the people involved in the marriage relationship just never learned how to really LISTEN AND SHARE. Communication, something we are all designed to do, all the technology we have, yet so many simply don't learn how to truely communicate, sad isn't it? Perhaps we should all learn to have therapist skills, which means ACTUALLY LISTEN AND VALIDATE OTHERS. We love to have that take place, ofcourse because we are humans and humans thrive on that.

If you think about how this sharing with this therapist brought you to having very real feelings for her, there is a significance to this that is being missed here. I have heard of a few men here that had tried to repair a marriage and it just didn't work. And that was because the foundation was never really there. It doesn't have to work out like that, it is often that many simply do not learn good relationship skills. And what I am saying here, is you actually learned some of that with this therapist that you could utilize in other relationships, because you aready know, IT WORKS by WHAT YOU FEEL.

What would be helpful is if you were able to learn from this therapist how to adjust interactions so that you could work on interacting yourself where you don't have this strong attachment happen but you DO FORM good relationships, like friends etc. What I am talking about is thinking about how SHE helped you come out and open up, learning the skills SHE used for yourself. That would be very helpful and actually be something you could utilize YOURSELF in your own relationship building.

Think about this, try to set aside this love thing and think about the whole picture if you can. Don't be hard on yourself and feel rejected here somehow. You are HUMAN and THIS DOES HAPPEN but you can actually rise above this and LEARN somethings. I personally feel you should be honest with this therapist and tell her that you need to learn how to work through these feelings instead of being confused.
