I found a woman with a nickname in my husband's mobile phone and called him after midnight 12. I answered the phone and hung up silently. I thought it was business.

There may be a problem. You should stare at it, or talk to your husband when you are free, such as whether you have done anything sorry for me recently, whether you have met any attractive women, whether you want me, and so on. Sometimes the temptation of joking won't hurt feelings, and you can be spoiled. The effect is quite good.
