I have been having trouble getting along with my husband, and now I meet a mistress. I insist on divorce. I just drew the fourth sign. I don't understand. Is my insistence correct?

Intellectually speaking, it is divorce. You said it yourself. There's always a problem. Do you want these problems to last a lifetime? Ask yourself if you can spend your whole life with such a person and have a companion when you get old. This is from a rational point of view, but from a realistic analysis, such as whether you have children, your age, and whether it is easy to find a suitable one after divorce. These are all things to consider. There is also the fact that the existence of mistress must be examined accurately and not wronged. Next, you should carefully analyze these reasons. Anyway, I hope you don't regret it and find the happiness you feel!
