The statement "The best things in life are free" implies that love and marriage do not come with any monetary or material cost. However, this statement is not entirely accurate when it comes to love and marriage. While love and companionship may not have a monetary cost, there are certainly opportunity costs that come with being in a committed relationship.
For example, married couples often have to make sacrifices in terms of their personal freedom and independence. They may have to compromise on their career aspirations or relocate to be closer to their partner's family. Additionally, they may have to make financial sacrifices such as purchasing a larger home or taking on additional expenses such as a mortgage or child-rearing costs.
Furthermore, a married couple may also have to make sacrifices in terms of how they spend their time and how they prioritize their relationships. They may have to choose between spending time with their partner's family or their own family, or between spending money on a romantic vacation or saving for a down payment on a house.
In conclusion, while love and companionship may not come with a monetary cost, there are certainly opportunity costs that come with being in a committed relationship. The statement "The best things in life are free" does not take into account the sacrifices that one might have to make in terms of personal freedom, finances and time when it comes to love and marriage.
