Wishing your therapist was your mother is common around here as I am sure you have realized in your reading this thread. It is nothing to feel ashamed about and it is a very natural occurance in therapy given its unique setting. So I hope first off all that you feel assured of that.
What happened with Charlotte is not a typical therapist reaction to what is simply labled transference. All and all, despite her tremendously difficult experience, her T handled her peticular situation in a very appropriate manner and I believe that she would tell you that herself, but it was certainly painful nonetheless and I understand your worries as far as that goes. It is a client's worse nightmare to feel rejected and abandoned by their therapist especially after disclosing such personal and sometimes humiliating feelings.
There is so much to be said about transference it's impossible to know where to start w/o knowing what you are already aware of and what sort of questions you have. I assume you have already read Shrinklady's page on transference on her website? If not that is a good place to start. Otherwise I could write novel about stuff you already know when you might in fact have a more direct question. And I don't want to do that to you.
I am 43 years old and I wish my T was my mom too. I really do. And I told her this and other transference feelings and she is ok with it. But this is something that YOU have to be ready to disclose and that is based on your trust and what you already know about your relationship with your T. I was in therapy for 3-4 months before I told my T what I was feeling and that is because it was tormenting me and I thought something was wrong with me. I confessed my feelings eventhough I was terrified she would terminate me. I even told her that and she assured me that would not happen. She was very gentle and understanding.
She also helped mme to undertsand that having transference feelings and trying to act on them are two different things. We can work through transference but if it becomes an obsession to act on then that is what becomes unworkable. And eventhoughit feels obsessive sometimes, I am not inclined to act it out. I hope that makes sense emerald.
Can I ask, how long have you been in therapy?
If you have any further questions please feel free to ask and to post all you need.
