Lemon it sounds maybe like he's just not able to empathise with your point of view. And that's really tough to experience. I saw a T who didn't always reply to emails and never seemed to understand how this felt and what it symbolised for me. He sounds very matter in fact in saying 'What do you want?' rather than getting to what is driving your feelings and really listening to how this is for you. It doesn't mean he will necessarily change and start replying to emails or being consistent about contact during breaks but the way I see it, maybe he needs to show more empathy and validate your experience of this situation. I'm sorry you're going through this. I know with my ex T, it felt like banging my head against a wall all the time, then when I tried to address it (in long letters) she would get defensive. Ugh.
