So here is the who, what, where, when, how, and why of expressing your emotions:
Who = I. Take responsibility. You're the only one who can make you feel a certain emotion. Say, "I feel ."
What = I. Take responsibility. It's your experience, not his. Say, "I experienced ."
Where = appropriate place. Agree with your partner on the appropriate place to share emotions.
When = appropriate time. Agree with your partner on the appropriate time to share emotions.
How = appropriate tone. Agree with your partner on a respectable tone to use with one another.
Why: to actually be heard. He's more likely to listen when it doesn't come out of left field; when you take responsibility for what you are feeling about your experience, in the agreed upon place, time, and tone.
