One of the golden rules of relationships is "don't criticize" your partner or mate. Stop and think before you speak. Criticism will get you absolutely no where. When you criticize, it becomes a personal attack on your mate. What happens when someone criticizes you? Criticism only angers you. Instead focus on communicating how their negative behavior makes you feel. Help them understand why a particular behavior upsets you. Explain how it makes you feel, so they understand why you feel they way you do. Effective communication will help your partner understand how you feel without making your partner feel like you are launching a personal attack on them.
