There is definitely more than one way to do therapy, and really, 4 months is not that long of a time.

Obviously your therapist is a relationship centered practioner, but not all are like that.

If you do think you have some emotion or some hint of an alliance with her, but you are stifling it, that is one thing.

However, if the notion of developing a relationship with this person does not seem to be understandable, or productive for you, then perhaps another approach would be preferable.
