What a terrible photo! You can't see anyone's face, the guy seems like he could be good looking but who would know with that massive sun glare over his entire face and hooded person on the left has the biggest sunglasses I've ever seen even though they're facing away from the sun. I would fire this photographer immediately.
Relationships are easy.
All it takes is for both people in the relationship to put in the hard work to constantly maintain the relationship. Simple.
Both sets of my grandparents really didn't seem to like their spouses very much, I don't remember witnessing any affection or kindness and my grandfathers especially were honestly pretty mean to their wives... and we spent a lot of time with both sets over the school holidays. So, given that, when my parents got divorced while I was a teenager, I knew it was a good decision and they were both much happier in the long run.
I also wish that we as a society didn't have such negative feelings about relationships ending. It's totally natural and honestly, it's fine. I think part of the reason my own relationship has lasted so long is because we both know that we can leave at any time, and so we both want to put in the work to try and be the best possible person for each other, and if it ended tomorrow, that'll be sad, but it'll be okay.
