The two couples are separated, and he doesn't reply to the message sent to her husband!

If it is staged, it is normal. When a person is under pressure to work in a different place, when things are busy, he is generally afraid of affecting his family's mood and will temporarily avoid communication. In addition, there is no reason to back down when the SMS reply time is short. In this case, it is not easy to reflect on your past with each other. It is not easy to maintain the feelings of separated couples! Give priority to tolerance, don't care too much about small things.
