First of all, we should realize that although his wife Xiao Zhao and her husband Xiao Liu have had emotional conflicts, they still belong to the de facto husband and wife. In this case, neither party has the right to choose to terminate the pregnancy unless an agreement is reached through the recognition of both husband and wife. Maybe his wife Xiao Zhao thinks that the baby is in her belly and she has the initiative, but this practice doesn't take into account her husband's feelings, and she didn't ask for her consent before doing so.
Moreover, we often say that marriage is not a child's play. Many times, there are quarrels and contradictions between husband and wife, just because of a temporary impulse. Since two people choose to have children, it shows that their previous marriage was well thought out and they think they are really suitable for each other. In this case, Xiao Zhao, as his wife, terminated her pregnancy only on impulse, apparently without considering the feelings of her husband Xiao Liu. In fact, it constitutes a violation of the husband's reproductive rights, so in this case, I think both husband and wife should communicate well, but for this fait accompli, Liu Ye should not be too bitter, or should treat his wife with a more tolerant attitude.
