Not unreasonable Redsmudgy, because our feelings are what they are, but because this has bothered you I would encourage you to simply be honest with your husband. There's no harm in saying to him that you know it to be true that he loves you, but just occasionally you would like him to say the words.
My mother freely told me that if abortion had been legal when she found she was pregnant with me, I would never have been born. She has never told me she loves me and I don't believe she ever did. (In fairness she has never told any of my siblings she loves them either.)
My husband and I were friends for a long time before we started going out together as a couple and it then took him quite a while before he told me he loved me. I knew that was because he needed to be absolutely sure of his feelings as giving words to our love would inevitably mean a lifetime of commitment. When he did get around to saying the words, it wasn't long after that he proposed to me.
