At first, you idealize, romanticize, and live in anticipation of something good, but then you face reality.

I have experienced this, but it didn't turn me into a gloomy, boring person who spreads their negativity to others. You need to be able to take hits, understand that things happen differently, and that if something doesn't work out once, twice, or three times, it doesn't mean you should give up and abandon life. There is always something good in life that will bring you joy and light your way, even if it's not the happiest path or with all the desired content.

And regarding happy endings, it's also debatable. You shouldn't base your opinions on such matters on silly couples who get married six months to a year after meeting, who haven't had time to really get to know each other and then realize that they were only connected by infatuation, passion, and other emotions/desires of a specific nature. It depends on the people, their compatibility, shared views, interests, etc. I have acquaintances who have been living together for several years, and perhaps there isn't the same emotional intensity as when they were in love, but there is love, and many other good things have emerged over time, bringing them joy and making them happy. And if you want to listen to someone about relationships and living together, listen to successful people in this regard, not nerds from a forum.
