If you find someone and want to make it work instead of looking over their shoulder for something better to come along, you have to make that commitment “for better or worse” - that it won’t all be highlight reels and advertiser-approved moments of elation, you’re going to see that person with all their masks off, see their petty mean spiteful side, their self-pity and illogic, their snot (and even worse) - and still make the decision to love and respect them.
People think all this will happen like (in the mundane sense) “magic” and that if they see anything they don’t like, that’s the green light to seek out something “better” (because surely out there is that perfect person, or maybe you can just use other people as masturbation tools and that will all work well) - disposable “me first, me all the time” culture looks great on paper, but does not seem to be leading to a huge epidemic of happiness.
Not to mention we’re having to import entire generations from cultures that still respect marriage and put family first.
The thing is, if you can make that decision and keep a dialogue about the fact it’s a decision and not a magic mystical thing that can’t be broached, you actually stand a chance at being completely happy, and yeah I know anyone reading this is going to be like “yeah right get back to me in X years’ time” - anything worth having in life requires some work, some effort, and some sacrifice.
If you find someone remotely compatible, the sacrifice will really only be the faked romantic ideal that things “should” just happen and fall into your lap, and that if that stops, you trade them in and look elsewhere.
