When I started therapy T said texts were ok and so were emails but she didn't respond. Then about 6 months in she said she had been reading a lot of information about privacy and now those things were not ok. We don't email much (4 - 6 emails over 2 years) and do sometimes text but 90% scheduling
Even though I don't use these methods for much personal, when she changed them it felt like a lot of trust became unstuck. It took about another 6 monthes before we were back where we were before. (A lot of issues came from ex t 1 and 2 and how they treated communication) Now we are both fully comfortable again. A boundary change can be overcome but I think you should be honest about how affected you are
Also I don't think you need to share more. I hear you.
