Therefore, it is important to understand what exactly the concept of "getting married" means to you, what meaning you put into these words: to get rid of loneliness, to increase your status, to make a step under the pressure of attitudes and stereotypes, often not realised, or you really have a desire to experience new deeper and closer experiences with your partner.

In my opinion, when we reach a certain age (and it is worth noting that everyone has his/her own age), we have our own personal sexual experience, we understand what we like and what we don't like, we are sufficiently realised in society, we are engaged in our favourite occupation, then we often have a desire for intimacy, deeper relations with our partner, a desire, for example, for joint travels, communication, a desire to get acquainted with his/her parents, a desire to live together and have children.

And how you name your relationship, it is up to your couple to decide. Whether you will register them in the registry office or not is also up to you. What rules will exist within your marriage, as you have guessed, also decide only you together with your partner.

Nowadays it is not a shame to be unmarried. It is shameful to aspire to be married if you don't want to be.

And about mistakes. A partner is not a mind reader. It is important to be able to listen, to be able to talk about your needs, to not limit the other's personal space, to be able to compromise, to be able to do something for your partner for nothing. Taking steps towards developing a relationship in your couple, registering your relationship is fine.
But the main thing is to take care of yourself and your loved ones
