If you answer the question “Why (for what purpose) do people start a family?”, then the ideal answers sound something like this:

I can't live without her (him)
I feel comfortable with him, I love him,
we love each other and want to be together,
we are together - a single whole, etc.
Ideally, people start a family because they love each other and want to feel loved in order to receive and give love. After all, to create a full-fledged, loving family, you need fidelity, love and responsibility.

But if you think about “Why (for what reason) do people start a family?”, then the list of reasons will be much more extensive:

material benefits from marriage;
unexpected pregnancy;
fear of loneliness, fear of being left alone towards the end of life or at the time of illness;
the desire to escape from a boring environment;
the onslaught of relatives and friends;
the desire to look more respectable and improve one’s status;
desire to raise children;
features of upbringing that prescribe that one must start a family (especially upon reaching a certain age);
envy;
an attempt to change your life;
the need for social guarantees;
it’s more fun this way (it’s more fun together);
there is a lot in common with this person (the same interests);
the desire to be “like everyone else,” etc.
There can be many more explanations for why people start a family, since it is connected with personal experiences and experiences, which are unique for each person.

Starting a family is one of the important choices of every person, which will significantly influence your potential opportunities in the future. This will greatly determine how much you can realize yourself as fully as possible. And any mistake, negligence or frivolity in this matter, with a high degree of probability, will lead you astray from the optimal trajectory towards your goal - and this is already a loss, and an irreparable one at that. After all, getting married is not just going to the registry office and getting a stamp in your passport, and then eating a salad in a restaurant. You will have to pay for the wrong choice.

If the basis for creating a family is wrong, then no tricks or technologies will help - everything will fall apart sooner or later. Psychologists believe that if a family does not have a unifying idea, then it is doomed to destruction.

Another important need is to discover one’s purpose when a person lives in a state of a bright creative flow, and it does not matter in what area: as a caring mother, as an artist, as an executive and responsible worker, etc. Every person strives to find his purpose, to realize his hidden possibilities. And where, if not in a family, can two loving people support each other in this natural striving for perfection?

To help each other fulfill their needs, we need to know and understand them. And here there is a problem: people often do not understand their own desires, and even more so they know little about what their partner needs. Taking care of each other's needs, giving and receiving love, sharing emotions, supporting in difficulties and doubts - this is what family gives and nothing else.
Any relationship is a clash between two personalities with different interests, desires, and worldviews. That’s why it’s so important for partners to clarify their needs and look for common goals. For this:
Discuss relationship goals at each of the four levels of needs: physical, emotional, intellectual, and spiritual.
Write them down.
Discuss from time to time, finding out whether all needs are being met and whether there is any imbalance.
And remember that even in close and trusting relationships, conflicts periodically arise. If you know how to communicate correctly during an acute situation, if you know how to solve it, then the conflict will make you closer to each other than before. Love each other, create families and be happy!
