It's ok to go bed angry.
(Don't believe that old myth never go to bed angry.)
When our basic needs aren't met our brains aren't working as clearly as they could be. Not really an ideal time to try to discuss something that we're seemingly passionate about.
However, before going to bed you could set up a time for following day to meet and discuss the issue. That way both of you know you're still going to work it out and you'll both be available and ready with full attention and a clearer mind. Then, get a good nights sleep!
(And just for fun, when I was having my husband read over this for me he suggested I give an example. I like this post just the way it is but I figure a little give and take right? So here is his suggestion for you all. Just like in school when the professors suggest you prepare for a big test what do they tell you? Get a good nights rest, eat a good breakfast and clear your mind.)
