Oh, I had the exact same feelings with my former T who used the same modality. If you're unsure about quitting, maybe stay for a little while longer because it can be very difficult to return if you quit then change your mind. I spent at least 2 months deciding if I was going to quit or not. What are some other reasons aside from boredom that are making you want to stop? Financial reasons perhaps? It's a hard decision to make because you know you must hurt the T's feelings regardless of how good your reasons are.
