Sincere sympathies, but you've learned some substantial things.
This cavalier attitude toward crucial requirements, possibly infected by inaccurate advice from others, will carry over into marriage (to you or anyone). Finances, for example, is a (if not the) chief cause of marital strife. He has not respected this. He also disrespected the need to prepare the apartment. Finally, he dismissed the need for, and the importance of, the police certificate.
At minimum, this indicates fundamental difficulties in communication between the two of you.
At most -- and realistically, in my view -- it indicates a crucial difference in attitudes toward responsibility and sacrifice.
Accompanying this is an apparent disparity in the effort put into making the mechanics of this relationship happen, with the concomitant effect on your emotional state -- and especially the lack of even token concern when you were sick. This is not what most people would call a sound foundation for a happy marriage or even a dating relationship.
You have the choice of deciding whether you can abide a lifetime of having to drag him through life's responsibilities -- the big ones, the everyday ones, and the unexpected crises that are inevitable -- and deciding whether you can overlook the mentioned deficiencies and never ever complain about them or bring them up again. The title of your thread suggests that you've already chosen your remedy.
The definitive decision is yours, but I think that the indelible handwriting is on the wall, and that you'll ultimately feel far better about yourself by calling a permanent halt to this enervating, expensive mistake. If you decide this, you can thank your lucky stars that this didn't proceed to an unhappy short-term marriage and the mess of divorce.
This world has innumerable attractive, appealing, responsible, supportive, emotionally available men who will willingly meet you halfway in forming a fulfilling lifetime relationship. Please keep this at top of mind.
