from what you are describing, it seems like she's just not into it anymore.
If you are ok bringing up your concerns with her, it may be worth the conversation (as you say you felt a connection to her, but it seems ot be waning).
I would be frustrated with these developments also, but again, a conversation sounds liek a good start. I know for myself, I interpret things through the lens of whatever it is I'm going through in the moment. If I am having a rougher time with things, and more triggered in general, I tend to think my T hates me or thinks I am wasting her time. When I am more balanced and less stressed, I tend to think we have a better relationship. I'm not sur if any of that is going on for you, but it may be worth getting her perspective on things.
If the conversation leads nowhere, or goes poorly, it may be time to switch T's or take a break. While it's daunting and exhausting to switch, it could also be really beneficial.
Either way, good luck, and keep us updated
Also, Ani reference in your sn?
