The perspective on whether the guilty party in a divorce due to adultery is "supposed to be alone forever" can vary depending on cultural, religious, and personal beliefs. Different religious traditions have their interpretations of divorce and its implications for both parties involved.
In some religious teachings, the guilty party may be seen as responsible for their actions and encouraged to seek forgiveness and repentance. Whether or not they can remarry may depend on their willingness to change, seek forgiveness, and adhere to the tenets of their faith.
Ultimately, it's essential for individuals going through a divorce to seek guidance from their religious leaders, faith community, or spiritual advisors to understand the specific teachings and principles of their religion regarding divorce and remarriage. Additionally, seeking personal growth, self-reflection, and seeking forgiveness (if appropriate) can be important steps for the guilty party to heal and move forward, regardless of their relationship status.
Outside of religious considerations, divorce is a complex and emotional process, and individuals experiencing it may benefit from seeking professional counseling or therapy to navigate the emotional challenges and find a path toward healing and personal growth.
