It may be difficult for my wife to quit the habit of going to nightclubs at once, but we can start by reducing the number of times, which used to be once a week, and now it can be changed to 1 month. After all, nightclubs are hard to go to too many. Tell her the nightclub is not safe, or don't go.
Step 2 go with her
If you are worried about your wife going to the bar, you can go with her. Even if she doesn't call you, you will stick to her and follow her. Maybe because you want to go with her, she will restrain herself and go less often.
3. Know her friends (especially the opposite sex)
If she often goes to nightclubs with her close friends, and the frequency is particularly frequent, you'd better know (investigate) and get in touch with her close friends, especially some male friends, to prevent problems before they happen.
Step 4 get her to make a commitment
Although it seems useless for a woman to make a promise. But at least let your wife know that you care about this, and she will have a bottom. Maybe she won't be so diligent when she goes to nightclubs, and maybe she will take care of your feelings more.
5. Call on friends around to persuade her.
Sometimes it's no use persuading yourself. Encourage your good friend to go with you. I believe that under the strong persuasion of her good friend and you, she will come to her senses and know whether it is important to go to a nightclub or family.
6. Take her out on a date
When you meet her talking about nightclubs, make time for yourself and take her out on a date. She won't dare to refuse you. You can act unhappy, and your wife will strike a balance between going to nightclubs and taking care of you in a bad mood. I believe she will choose the latter.
If she chooses to go to a nightclub, then I think your relationship will come to an end. You can consider divorcing your wife.
