I understand your feelings

since my ex left me because of his affair with another woman. However, this does not give me a right to judge others, because every individual case is different. For example, 妹妹 and Old Genger seem to be a good match. If Old Genger's wife is in depression and unhappy for 10+ years, she (Old Genger's wife) really has no excuse. In real life, I did see some wife like this. Old Genger spoiled his wife for too long. It is actually good for this ex-wife and her children to learn to respect others and learn to earn a happy life by themselves.

Well, again, I dislike Xiao3 San1 (the third party in marriage) very much. Personally I had and would never date any married man. However, I do not want to judge or teach others about how to live. They know their hearts and situations best.
