Very much this. I’ve been happily married for 25 years and expect to be for at least 25 more, and the things that annoyed us about each other when we were dating still annoy us today. But we accept that those things are unlikely to change, and celebrate the stuff that’s great.

On top of that, guys don’t tend to mature until they’re 21-25, but don’t start dating one who’s younger expecting him to change for the better; it’s more likely the common things you enjoy will change but the odd habits will remain forever.
