Congratulations on your choice to get married. Be advised that your wedding day will be the subject of the complaints of the ignorant and the jealous. I can say that, without equivocation, no one who attended my wedding who complained remain in my life, so I look at the event as a tremendously successful weeding-out test.
The struggle will be deep and real between the two of you, but the adage will hold true: as long as you have each other, there will be no end to strife. But those trials and tribulations will ultimately make you both stronger, fitter, and more appreciative of one another.
I have many complaints of my partner, but none of them come close to the threshold of my patience. I hope you will find the same with one another. In my mind, that is what will distinguish the anecdotes from wisdom, and your love from false narratives.
