3. Be self-aware and express empathy
You can hardly ever meet couples who have never experienced difficulties. It is absolutely normal to experience disagreement from time to time. Conflicts might occur. The point here is to learn to deal with troubles and worries without anger, aggression and fear. Do not blame each other if something goes wrong. Show empathy and control your own emotions. Be helpful and supportive. See how useful you can be in the situation. Stop fighting and spend some time reflecting upon what has happened.
4. Physical intimacy
If you want to be a happy couple, stay physically close. Physical intimacy is a very important part of your relationship. Do not avoid each other. Kisses and hugs are needed. Touch your partner with love and affection. This will let them feel that you are close to them. Married couples who stay physically close feel happier than those who avoid the contact. In fact, your love may intensify if you let each other express your feelings and emotions through touches and hugs.
