I'm learning through this process that emotions should be felt but taking action during the influence of emotions is usually a very bad idea. I have a hard time with it too...but am trying very hard to learn. Think of emotions as affecting your goals and reasons like a drug or drink maybe. Acknowledge your emotions and find a way to get them out (exercise, writing, friend support, sports, whatever...) but if you want to save your marriage, your W does not need or have a right to see your sadness, anger, etc.
I know it's easier said than done but one day at a time I guess. Good Luck!
