I feel it would be appropriate to mention this, to your T.
I'm also, rather firm about not growing attachment to my therapist.
The sweetness, aspect, may be an awakening for you, to seek out a friendship that is like that. A new found need.
We all grieve differently and crying isn't a requirement. Maybe, something else, will bring about a needed crying spell, if it's not the right time for you, it just isn't.
