A strange man appeared in my wife's WeChat friends, and she said he was a colleague, so I chose to believe it; my wife stayed up all night for the first time, and she said she was on an emergency business trip, and I expressed doubts; there were unknown bite marks on my wife's neck, and she said it was an insect bite, but I remained silent; my wife got angry and shouted for divorce, and she said it was too aggrieved, so I agreed; after my wife left the house, she knelt down and begged me for forgiveness, but she said she knew she was wrong, and I told her to get out.
