I don't know how many years you have been married. First of all, you are the closest person to your husband now. He shouldn't know who is more important. You should talk to your husband calmly. No quarrel can't solve the problem. You should explain these points to your husband first. One is that you have to tell your husband that you trust him and are firm. Second, don't be too sensitive when something happens. You should calm down and carefully analyze your usual feelings and life from many angles, such as whether you don't care enough about your husband and so on. Third, you should talk to your husband's female classmate. Don't be angry when you meet, but also talk calmly. There are two possibilities, having an affair and not having an affair If not, it may be that your husband is helping a divorced woman, and she may be in trouble. Whether or not, you must first make it clear that you love your husband very much and have firm confidence in maintaining your family. You should fight against all acts that destroy the family, don't destroy the family, and let her respect herself. Of course, if you hadn't said these words, she would have understood all the meanings. As for how to say it, how light and euphemistic it is, just hold it by yourself, which will show your atmosphere and ability to do things. It's best to talk to your husband first in this order, and then decide whether to talk to your husband's classmates according to the situation.

There is another situation that is the most difficult to deal with, that is, your husband and classmates don't admit it, but they still contact behind the scenes and unite to cheat you. Even in the worst case, my previous suggestion should be done, and you can do it. Emotional things cannot be compromised. If your husband loves you very much and is responsible for his family, he won't do anything to hurt you. You should know your husband best. If the worst happens, the right side is in your hands. You can choose to forgive him or divorce him directly and so on. However, divorce should be cautious. This is no joke. It is not easy for two people to be together. Look before you leap. Trust is still a prerequisite. You have done everything you should do as a wife. As for the latter hypothesis, it may not have happened at all.

Judging from your supplementary information, this situation is not good and has been for a long time. You'd better call your elders and your close friends to discuss whether you want this family or have anything to do with that woman, depending on your husband's reaction and attitude. You have to observe for yourself what kind of person your husband is. You'd better talk to that woman before you do that. This kind of thing, whatever it is, there is nothing to hide. If your husband is a man, he should confess. It's so ambiguous. He's married. I don't know which is important. Really. As a wife, you just have to have the courage to cut the gordian knot in this matter. You don't know what your personality is. This matter is urgent, and the sooner it is solved, the better.
