It won't last long. Marriage is not unilateral, because one party has never supported it. Even if your feelings are deep, they won't last long. After marriage, two families will be involved, and what you want to do will not be understood for a long time. This may be the reason for your quarrel, you will be more and more tired and your feelings will gradually run out. It's better to let go before it's too late.
Of course, if you two are firm enough, it will last for a long time, but I feel that this kind of situation is rare in reality, because there are many trivial things in life, which will gradually lead to differences, and with the support of one family, it is more difficult to go on steadily. These still vary from person to person. I hope you will have your own happiness as soon as possible.
