Sometimes getting a good nights sleep is all you need to be able to reset your head and better understand the situation at hand. This is especially true if your argument happens late at night when everyone is tired and not all there mentally. What the phrase should be is "Never go to bed without saying I love you". In my opinion, it is perfectly okay to say something like "I disagree with your point, I'm still upset, but I still love you and we can talk about it more in the morning" or something similar. #conversation source
