1. Open communication: Choose an appropriate time to have a peaceful and sincere conversation with your husband, expressing the coldness you feel and how it affects you. Ask him if he has any troubles or pressures, and if there are any areas that need to be changed. Maintain an open mind and listen to his thoughts and feelings.
2. Self care and improvement: Don't focus all your attention on his attitude, but put some of your energy on yourself. Participate in activities that interest you and enhance your sense of self-worth and happiness. A good self state will attract more attention and positive responses from others. At the same time, you can also try new ways of communication and interaction to attract his attention in a more positive way.
3. Seek professional help: If the situation still does not improve after communication and self adjustment, you can consider seeking help from a marriage counselor or psychologist. Professionals can provide neutral perspectives and effective communication strategies to help both parties better understand each other, identify the root cause of problems, and solve them. Remember, marriage is a joint venture between two people that requires effort and investment from both parties.
