One by one, one sentence cheers for the graduate school entrance examination Before finding another lover, the current lover is not necessarily the best forever. This is because love and relationships are dynamic, and people's needs, interests, and values can change over time. In addition, problems and conflicts in interpersonal relationships can also lead to estrangement between the two parties. Here are some of the reasons:
1.Relationship changes: Over time, people may become bored with each other, especially if there is a lack of freshness and stimulation. At this point, it may become more attractive to seek out other possible partners. 
2.Growth and change: Everyone is constantly growing and changing, and there may be a point in which both parties will find that they no longer match each other's expectations and needs. In this case, it is natural to look for a more suitable partner.
3.New opportunities: In life, we may encounter new people and things, which may make us feel stronger feelings for other people. In this case, the current lover may no longer be the most suitable partner.
4.Problems in relationships: Various problems can arise in long-term relationships, such as poor communication, uneven family responsibilities, and personality incompatibility. These problems can lead to a deterioration in the relationship, making the current lover no longer attractive.
5.External stress: Stresses at work, family, and other areas of life can affect your love life. In this case, the current lover may not be able to meet the psychological and emotional needs of the other person, which can lead to a breakdown of the relationship.
In conclusion, a current lover is not necessarily always the best until another lover is found. People's needs and feelings change over time and life experiences, which makes it challenging to maintain long-term stable relationships. However, by communicating positively, growing together, and adapting to change, couples can work to maintain their relationship and make it more long-lasting.
