They are human...and to answer your question, I don't know. I saw a T for 7 years and had the opposite problem. I had to fire her because she got too close and started "mothering" me instead of being my T. She would begin every session by asking if I had gone to class that day and then when I talked would tell me I was making bad decisions. So, I don't know.. but they are people too.

Maybe something changed in her life (that has nothing to do with you) but that causes her to have less time to devote to texting her clients. If it makes you feel better, I've never had a T who texted me to check in...
