I know it's probably not what you want to hear, but it sounds a bit like he's not being very considerate to your feelings at the moment, especially given the transference you have talked about. Phoning at night for example; it sounds like you're not getting the space you need. I sense from the tone of some of your comments you are starting to feel that way yourself.
Did you say you have a new T? What do they think about the way old T is acting? Is there an element of unresolved countertransference involved?
I hope you are given the necessary space to grieve MASIMO. It's such a painful loss
