It doesn't matter how clear she thinks she's been about the boundaries, if her client doesn't understand fully when to call and is asking for clarification then she needs to give that.
It is natural to want to call her and tell her when you've achieved something positive but I'd agree with her that that type of thing can wait until sessions. However, telling you to use your judgement about what you can contact her about isn't her being clear, cos your idea of a crisis and hers could be two very different things.
Her statement of her boundaries sounded quite defensive or rejecting and a bit shaming of you. At least that's how I'd feel.
I can understand that she doesn't want to create a dependancy in you, and that's why she discourages you seeing her as someone you can call with good news or life events but some degree of dependancy is normal and just one stage of therapy if managed effectively. She doesn't sound very available, are you comfortable with that?
