The reason why human beings are different from animals is that human beings have thoughts, they can think about why they exist, they can think about why they do something, instead of being driven by biological instincts, or oppressed by other external factors, and dealing with their own lives at will.
So what you should think about when you get married is what kind of partner you want to live with, and what you can do to find that partner; what kind of married life you expect, and what you can do to realize the ideal married life. Choosing to get married is choosing how you want to live your life for some time to come. Your own life, you have to do the thinking, have your own ideas and goals, and then try to realize them.
Because of the urge to find a nearly married, you have to think clearly, what may be the results, these results whether you can all take responsibility for yourself, or even whether you can pay for the responsibility of others. Always remember: one's freedom is always predicated on not hurting others.
