Women actually. They are taught they do not need to settle down, and they are shown examples of how beautiful life is alone. And they believe it. They try it, and it works for several years, then things start to fall apart. It's a common trend in the west, and because of this people are destroying themselves.
Women have timetable in terms of procreation and biology eventually wins.
The Western concept of "independence" or being "alone" is based on the premise you can do everything you want and no one will stop you from doing so. It's not Godly because it elevates pride and ego and not having to care for the needs of another human being. You can make all the noise you want, waste all your money and no one will complain. It's the opposite of humility and idolization of oneself.
While Jesus and Paul clearly say being single is better. They're not really alone. They're always with people so they still need to be sensitive to the needs of others.
While Jesus often retreated to the mountains or the wilderness to be alone, it's only for a short moment. To be responsible for other people and even living among other people builds character. You don't have to be married to become responsible for someone or others.
So in many ways, marriage can be better if you are unable to make good use (one that the Lord will approve of) of all the free time and free resources you have as single.
