As you probably remember (as you replied to my thread at the time) I've been through something very similar recently. Transference, attachment, feeling rejected, hurt, wanting to terminate, taking a break, the whole horrible blah.
I'm currently on a break from T (doesn't quite feel like one yet as we would have been breaking for xmas anyway) I had an initial session with a second T and I'm seeing him again next week. I'm mainly wanting to work through the transference with new T and return to my old one. Although I already miss my old T, this has been such a good decision for me. It has given me the opportunity and motivation to examine my feelings for T and why they can cause me such hurt. I wrote him an honest and detailed letter about my feelings for him. I don't intend to send it but I might read it to temporary T. It was really cathartic.
I also think that old T appreciates working with me a bit more as a result of this. In our last session he said "I have learned so much from working with you, professionally and personally, so I'm losing something too". I sort of think that when I go back to him, the little ruts we were both getting into will have improved, especially if I can go to him with greater honesty about the roots of my transference. Like your T, my T seems a little defensive about my feelings and has said hurtful things.
I think what I'm trying to say is that if you feel a break is the right thing, you might be right. I don't know if you feel the need to have a temporary T to help you work through stuff in the meantime, but either way, space might do the relationship some good.
Good luck with whatever you decide, and happy new year!
