I think the fact that your therapist knows everything (besides his name) is really good because you are hearing from a professional (rather than just us) that what he is doing is wrong. I am sure both your therapist and stepmom have said this, but don't answer his texts these next few days (or ever! ). You need to do your best to try and make sure he can't manipulate you back into this. I think these next couple days will be the hardest but once you get through them your head will be much more clear and you will realize you do not need him.
