How often were you texting and e-mailing your T, and how often was she texting and e-mailing you? Perhaps the problem your residential treatment team had was not with the principle of e-mailing/texting, but with the frequency of contact and the dependency it was creating. There do need to be boundaries around outside of session contact so that the therapist and client do not become too enmeshed in each other's lives. With a lot of contact, especially informal contact like texting, the roles of client and therapist can become blurred and the T can start to feel more like a "friend" which is not conducive to a healthy therapeutic relationship. This is especially important with younger clients. The role of the therapist is to help the client gain independence and learn self-coping skills; by meeting your needs rather than teaching you how to meet your own needs, your T could actually be doing you a disservice. It's also possible that your T was playing too much of a "mother" or guardian role in your life, which was interfering in or detracting from your relationship with your actual family. If a client is still underage and living at home, it's the T's job to help the client get along better with their family and repair those relationships so that you will have a better home life. However, if the T becomes too involved, it can feel to the client that she is the "only one" who understands, while the family does not, and this can cause a rift between the client and the client's family. This then becomes an impediment to healing. Alternatively (or additionally), if the client has erotic transference for the T, and the T encourages frequent texts and e-mails, this can encourage the client's exaggerated feelings and fuel an impossible fantasy that can get in the way of healing. If there is erotic transference happening, it is especially important that the T NOT encourage enmeshment, frequent contact, etc. In these situations, the T needs to hold stricter boundaries in order to allow the client to work through the transference and use that experience as part of healing (as opposed to unhealthy enmeshment). I realize that I don't know the details of your situation (though I have read many of your previous posts); these are simply some possible reasons as to why a treatment team might insist on terminating the relationship between a T and client because of boundary violations.

As far as texting and e-mailing between a T and client, I can give you an example of what my T (and her colleagues) consider "healthy" or "within appropriate boundaries." With me, since I have never had issues with boundaries, she says it is okay for me to text her "once in a while." This generally amounts to 1 to 3 times per month outside of session (and she responds). She considers more than once a week too much, because it encourages dependency on the therapist and does not allow the client to develop self-coping skills. My T allows e-mail, and I have e-mailed my T three times in two years (and she responds). She says that it would be okay to e-mail as often as once a month, but no more than that. She says that when she works with clients who have issues with violating boundaries, she does not allow texting or e-mailing at all, except in emergencies or for the purposes of rescheduling appointments. I realize that a lot of people on the forum have more frequent e-mail and texting contact with their T, but that is not typical of therapy relationships in general. And, while my T recognizes that she doesn't know the circumstances behind other T-client situations, in her opinion, more frequent outside of session contact can be enabling and not in the client's best interest. She says that, as a T, the best thing she can do is help the client become independent and stand on their own two feet.
