Hate the way I love you

When was the last I said 'I love you' yesterday or a while ago? Have you ever say it before? I thought to love someone is more than just saying those three words. As for me, I believe that words don't really matter long as your feelings are on the same page. But why do I feel so empty not hearing those words coming from you, instead of hugging and kissing all the time try to convey your feelings using I love you?
