no it is not always transference... here where I live just general in love with therapist is called attraction, attachment. if the in love with therapist is a situation where someone is actually in love with someone else but transferring that love to being the therapist then its transference....

taking it out of love for a moment so you can see what I mean... if I am angry with my wife but I instead take it out on my co worker thats transferring my anger for my wife to my co worker.

if Im angry with my wife and I let my wife know Im angry and Im not taking my anger out on anyone else thats not transference.

see what I mean .... think of transferring like an object moving that object from one person to another.
