A crisis can start in different ways, everything is purely individual. A crisis is a rather difficult phenomenon that simply needs to be dealt with. Of course, crisis is better prevented than cured.
In the life of spouses, a wife should be interested in and share her husband's professional interests, be proud of his achievements. If there are no special achievements, then you should not focus on this. Encourage your man to do what he likes. Also let him get enough rest, especially if the job involves responsibility. Insist on proper rest, which will be directed only to your joint desires.
During a crisis, there is no need to remind a man of his age or hint at it. Do not write off poor health and fatigue on age, let the reason be the rhythm of life, work, ecology, whatever, just not age. Talking about age can trigger a crisis. This applies not only to men, but also to women.
During the onset of a crisis, patience and wisdom must be exercised. Watch yourself, attract the attention of your husband, but do not be jealous of him, talk more often.
If the wife is in a crisis situation, the husband must support her in every possible way. Say compliments, nice words, admire her beauty and intelligence. A man always has the opportunity to help a woman in the household. Of course, these are not such interesting activities as playing at the computer or sitting in front of the TV, but a man must understand that in addition to his main job, the whole house is on the woman, and the man is quite capable of helping her sometimes.
Give the woman a rest: let her have the opportunity to attend interesting classes, meet friends, go to courses, to the theater. Give flowers and gifts to women more often. After the crisis is over, everything will fall into place. This means that you honestly passed the test for supporting each other. This will add reliability and understanding to your relationship, since together you have passed all the tests and saved the family. Together, you will continue to change your life and environment, you will trust each other and enjoy your age.
