i don't think you should. she's right: this is a professional relationship and you need to move on from it. it is quite common for patients to become attached to their therapists: it's called "transference". for more info look at http://en.wikipedia.org/wiki/Transference
. although this mentions psychoanalysis, it can occur during other therapeutic relationships and your therapist would acting very unprofessionally if she continued a personal relationship with you. if it were found out, she'd probably lose her job, apart from anything else.
she probably won't be angry if you raise the matter again, but no matter how often you raise it, the answer will be "no", hugs, Judith xxx
