My cousin married my husband's brother, and now I find out that he is having an affair. What should I tell my cousin?

What's the big deal? Think this is our own fault.

When she realized that her husband was having an affair, she didn't want others to know.

So you can talk to your husband now.

Tell my husband's brother it's not good.

Stop it, unless you want a divorce.

Because sooner or later, someone will know about you

No one will know unless you tell me.
