I think this is going to depend a lot on where in the world you are.
I’m from the mid Atlantic/northeast US, and was raised catholic, overall I wouldn’t say that around me there was ever a separate “Catholic dating culture” it was just catholics dating other people who may or may not have also been Catholic. Not any more problematic than the rest of the general dating pool in any particular way
In other parts of the country or world I suspect that may be different
I’d be pretty hard-pressed to name any of my friends who graduated “on time”
I’m well into my 30s now, a couple of my friends are still working on degrees or just graduated.
Changing majors, bullshit scheduling nonsense, life
Shit, there was a whole fucking pandemic that fucked up a year or two of your high school years, it’s pretty damn amazing that anyone your age is graduating even roughly on-time as far as I’m concerned.
Maybe it’ll throw a bit of a monkey wrench into your social life because you gotta skip out on a couple things because you have class. That’s life as an adult, we all got scheduling conflicts all the time.
Otherwise, it’s never gonna matter. You’ll have a degree, that’s the only “important” thing about graduating. Unless you’re looking to get into some highly-specialized, super-competitive field, no one gives a shit how long it took you to graduate, how your gpa stacked up against the rest of your class, etc. It’s like the old joke “What do you call the person who graduated at the bottom of their class in medical school? You call them ‘Doctor.’”
