I have no idea. It isn't an unusual thing to develop a crush on the one who fulfills some of your psychological needs. I suspect T can help you with it. He/she has had it happen before with other clients. Otherwise, you can consider getting a different T. I wouldn't suggest trying to work through it yourself because I think therapy will be more productive if you two work on it together. I hope you manage to find a way to work through it with your T.
