First, selfishness
Selfishness is a significant cause of tension in remarried couples, primarily manifested in the desire to control each other financially and economically. If both partners have children, they may frequently criticize the other's children and show favoritism towards their own. This tendency to control finances and favor one's own children easily breeds hostility between the couple, leading to marital instability.
Secondly, comparative psychology
They often compare their current spouse to their ex-spouse. In these comparisons, they frequently feel that the former was superior and the current spouse is inferior. This is often the trigger for many family conflicts.
Third, inferiority complex
Some people (especially women) are heavily influenced by feudal ideas and believe that divorce is a shameful thing. They feel inferior and lack confidence in life after remarriage, become listless, and even unwilling to interact with others. They stay at home all day, and over time, they lose many friends and are prone to depression and other illnesses.
Fourth, jealousy.
This mentality is more common when both partners are remarried, with men being particularly prominent. They harbor resentment towards their spouse's previous marriage and frequently express it in various aspects of life, severely damaging their partner's self-esteem.
Fifth, nostalgia.
This situation is often seen in couples who had a good relationship after their first marriage. However, if their ex-husband or ex-wife dies in an accident or illness, their deep feelings cannot be forgotten with the passage of time. As a result, they often express this sense of nostalgia after remarriage, which can easily cause dissatisfaction in their new partner.
Sixth, arrogance
Some people have an excessively strong sense of self-esteem, and after remarrying, they become self-centered or use their pride to mask their inner imbalance, which manifests as subconsciously ignoring their partner's presence. This easily leads to conflict and causes their image to plummet.
