My girlfriend called another man's husband on a short message, and that man was his friend. The chat between them is also very ambiguous. What should I do?

Since the landlord can raise this question, it proves that the landlord does not want to break up. I want to find a solution to this problem, but as the saying goes, a leopard cannot change his spots. That's probably your girlfriend's personality. You can't change her current personality. Even if you try harder, you will look so pale and powerless in front of her personality. So I suggest that if you really love your current girlfriend to death and can't live without her, you have to try to accept her personality. Try to believe everything she tells you. Even if one day you feel cheated by her, please don't hold a grudge against her. Because that's the family you love, but you can't live without them. So being cheated is also my own reason. It is love that makes you lose your normal judgment. Of course, if the landlord thinks he can put it down, then I personally think leaving her is the best solution. If a woman doesn't even know how to respect her boyfriend, it's not a pity that such a woman lost it. In other words, if she really loves you and cares about you, she won't call a man that. After all, we are from China, and we are not as open as the West.
