Is it possible to get married “for real” from there?
Can. But this requires certain prerequisites.
Firstly , initially negotiate “on shore”, discussing all the nuances and deadlines.
That is, while you are still at the dating stage and are not moving in together, agree on the conditions: you try to live together, run a joint household, etc., but there is a certain period. Let's say six months or a year. After which you either register your relationship officially, or...
But you really need to be prepared for any outcome. You may have to break up (at the end of the term) - so be prepared to do this too. Why waste your time and his respect?
Secondly, it’s important! Do not live with a man on your territory, especially in a civil marriage. You will stop respecting him, and he will stop striving to achieve something on his own. A less dangerous, but also not the best option is to live with one of the parents. A young family should have at least a small, rentable, but its own territory. If it is not possible to live on a neutral territory or its territory, I would not advise moving in together at all.
Thirdly: paradoxically, the more you are afraid of losing a man, the greater the chances of losing him, and at the same time the remnants of your self-esteem and self-confidence as a woman. Therefore, no matter what happens: stay true to yourself, remain yourself, and if something in your relationship with a man does not suit you, either change yourself, or negotiate with him, or change this man for another.
There is no need to cling to a man, agreeing to live with him on his terms, if you don’t want to. Your relationship, and especially your life together, is a conscious choice of two adults. If the idea of civil marriage in principle disgusts you as such, just do not initially agree with the motivation “living together for me is only a legal marriage.”
