Hi!
Answering your question, there may be two types of early marriage, either because it is a marriage of two young people or just early to get married within three months of knowing each other.
Love is something complex, love is a feeling that nobody chooses to feel, it just comes when you least expect it and it catches you in a way that you can not control, it is a very strong feeling, it makes you love a person as much as you You yourself, make you love your virtues, your defects, your secrets, your dreams, your fears, is something that you can not simply explain with words but with feelings, with feeling.
I have always said that there is a person created to measure for us, who is in the world and that we may take to get it or get it very quickly. While you can not get it you can have relationships or experiment with other people but you will never feel that desire to want to marry and form a shared future.
When you get that special person, that person with whom you make a "click", love and feeling is felt, and that can happen you are 15 years old, have 20, have 30 or even have 50 years, age is never a problem, that is why today there are relationships of people who are together since age 15 and at 28 it is that they decide to get married and not because they are not sure of doing it, but because they already know that this is their ideal person and that Special moment can last.
A couple can get married within months of knowing each other but honestly to me that seems crazy to me since you are not giving yourself the time necessary to know that person well, to know their fears, their virtues, and their shortcomings, to know their past and know what you want to have in the future, in fact you do not have time to know if it is your ideal partner who has been waiting for you, and that is why many marriages fail.
The first months of a relationship are the perfect months, the fights are few, the problems are non-existent, and even there are no defects, there you decide to marry your partner and after a year you realize that you start to fight, you do not tolerate living with That person, and you do not feel completely in love, so you decide to divorce, and you realize that this was not your ideal partner.
I am totally in favor of relationships that start at an early age and last for years and decide to form a life together.
That's why I say that marriage does not depend on the young age but on the time with which you meet your partner
So I would recommend everyone dedicate time in pairs to get to know each other, dedicate time, know virtues, defects, and learn to live together and respect each other
regards!!
