I think I will still love you as much as I do now in fifty years.

If you are going to get married, in 50 years, love will become a family relationship. That is the person who will accompany you to the end, and you will be inseparable from him. This should also be love. If you love each other but are not together, it is meaningless to say these things. If you love him, you must protect him. I think no matter how hard it is, being together is happiness.
