If not, there are only three situations, cheating, gambling and drug abuse. You know what the most likely scenario is.
But in either case, such a woman can no longer be wanted. If you go to the court to file for divorce, it will be a disaster for you to be late, and you may owe a debt waiting for you to pay it back.
Family and marriage should be run by two people together, so that the preservation period of marriage will be long. Are you not good enough in some ways? Not caring enough to take care of her? If not, then she didn't do her duty. Although it is understandable that one of the married couples yearns for freedom and relaxation, she always leaves her family behind. If it's not your own fault, then she really lacks a sense of family responsibility.
If it's really her fault, please take a long vacation, take the children to have fun, walk for a long time, for example, for a month or two, go to the place she once wanted to go, eat what she once loved, take photos and bring it back, just pretend that she doesn't exist, take the children to continue living, then sign up for a class after life, and take training classes, yoga or swimming and playing ball games with many beautiful women, and so on.
