'She used to text me with smiley faces and exclamation points (just reminders about therapy, or answering if I had to change an appt). I noticed though, that the past few months, she hadn't done that and it made me feel disliked. I never brought it up.'

Did anything occur during the period that her style of communication changed? Did it change when you started discussing the possibility of termination? If so, it may have just been an attempt to achieve some distance so that termination was easier... If it wasn't that then we need more info. It seems unlikely that she would have just gone from 'like' to 'dislike'! Personally i get very stressed about people suddenly not 'liking' me anymore, but from an objective perspective i can now tell that this has to do with self-worth, insecure attachment patterns and such. It has very little to do with the other person's actual feelings.
