I don’t necessarily disagree, and everyone is different, but you should consider that it’s not just you that changes. You change WITH your partner. You grow TOGETHER. I am absolutely different than I was 10 years ago, and so is she, but that doesn’t mean that we’re no longer compatible. Our growth contributed to each other’s growth.
I do think people should be maybe… less attached? You should regularly evaluate your relationship to see if it’s working. Shared interests aren’t even always necessary (as long as they at least show interest in what you like and vice versa). But that is very hard and many people would rather not be alone.
