If I may offer an opinion? Does his actions show platonic love?

My T hasn't ever said "I love you", and she also resists saying explicitly warm things like "I care about you". I've been the one asking her if she loves me according to my stated definition of love. Even though the words "I love you" has never been said by her, her actions fit all of my stated definition.

I do get the strong wishes to hear the words though! I would really like T to say the words. If she ever said it, I'd want her to say it again and again and again.

My parents, if they say the words, say the words "love you" mechanically with no feeling. And their actions definitely don't show love. While T's actions do.
