Talking and communicating your emotions are two different things. Communicating with a  difficult partner is especially hard when you fight with them. If your spouse is difficult, you need to cool down and deal with things calmly. Stick to the issue, don't let other issues be included in the conversation, and let your partner know how their actions or decisions have affected you and how you feel about them. Don't play the blame game, or they'll show defensive behavior. Communicate calmly and clearly and make sure to listen attentively.
