Given the above summary, write a detailed text in English for it.
Tell the person, in direct but not harsh or dramatic terms, how their behavior has affected you.  Try to focus on yourself and your feelings rather than the other person. For example, instead of saying, "You sabotaged our project at work," try saying, "I noticed that our project wasn't the best, and I want us to be sure it is better next time." When you talk to someone and tell him that his behavior is hurting you, it is likely that he will deny everything (remember, passive-aggressive people don't like to talk about their feelings-- they certainly don't like to be called out about them!). Stick to facts and give examples, but be prepared for resistance and denial. A passive-aggressive person might harbor feelings of low self-worth or issues from his or her childhood that makes it difficult to communicate feelings effectively.  Talking together can help you understand the possible roots of the passive-aggressive behavior, if the person is willing to open up a bit and you are willing to suspend judgment and be understanding.   Ask questions about his or her childhood, youth, early relationships (especially ones that might have ended badly), or other life scenarios where speaking his or her mind might have backfired. Remember, passive-aggressive behavior is often a coping strategy used by people who have had negative experiences that left them feeling helpless or powerless. Depending on how a person responds when confronted about their passive-aggressive behavior, you might realize that there is a good chance of salvaging the relationship, or that this person is rigid in his or her ways and unlikely to change. Many times, avoidance is the only strategy that can use to avoid being a victim of passive-aggressiveness. But if the other person recognizes the problem and is willing to work on it, there are many ways to improve your relationship by working on your communication strategies.
