The way it was taught to me is that we don't talk about Her much because Her name is extremely sacred, and Heavenly Father does not want Her name dragged through the mud and abused like His is. Therefore it is out of great respect and reverence that we spare Her name. She understands this, so She is not hurt because we don't use Her name much. Beyond this, I would venture to say that She is well-pleased that we respect Her so very much. What I do is reverently ask Heavenly Father during private prayer that He would make known to Her my great love for her. Some would say that's corny, but it comforts me. I see no reason to be sorrowful about the Church not mentioning Her much. She feels our devoted love, just like Heavenly Father does.
