My T is the 3rd person I have ever told I loved her. It wasn't a big deal, I just said in in a context.
I am not a native speaker of English, and in my language, we have several different words for expressions different kinds of love. So, for me, saying I love you comes especially hard because I miss that difference.

I would not ask my T if she loved me.
Why?
Because it's a tough question for her. She doesn't know my exact definition, and in the end, I don't know if the answer would even be anything I wanted to hear, even if it were a yes.
I may ask her for actions, ask her to do something for me. To me, those actions show her caring for me, and for now, I think that's all I should expect. I know my feelings for her are likely more intense than hers for me, even tho I do get the impression she likes me as a person.
