Idk if it makes sense or not

Had a fight today, and she asked me "don't you have a fear of losing me?" I said, "No, I don't fear losing you ever, but the grief of losing is more than the fear. I don't have any fear at all of losing you, it's more of a grief that I will experience about what we both have lost". I just don't know if what I just said made sense or not, but I really never had any such fear, it was always been that if this ends, the grief of losing her is what will make me cry one day. It was greater than the fear. And then, she said, I got my answer, I don't think this can work.
