Many Buddhists do get married and have families. In Buddhism, marriage is generally seen as a secular affair and is not considered a religious rite or sacrament.
It is up to individual Buddhists to decide whether or not to get married and, if so, how they would like to conduct their marriage.
Buddhists may prefer a traditional wedding ceremony, while others prefer a simpler or non-traditional approach.
Ultimately, deciding to marry and how to conduct a marriage is personal and based on the individual’s values, beliefs, and circumstances.
