Can I see the content of his short message by binding my husband's mobile phone number?

It's not necessary. It's not betrayal to do something outside. As long as your husband is kind to you, you can play dumb. If your husband is having an affair, the key is whether you have feelings for your husband in your heart. If you can't be together, you can choose to break up, or you can keep your family and save your husband for your children. You can also find another true love, but you can't get along with your husband. Of course, you have to find out the reason for the affair first. It's your husband's fault. You can't handle it anymore. I am on your side.
