I suppose I did the "way younger" thing. But in my defense, I pretty much end up with people roughly the same age every time when talking relationships. Which is funny in that I get older, but for some reason the people I end up with are more in a stasis in terms of age.
Consistently I end up with women who are around 20 years old. When I was 18 I ended up with someone who was 22, when I was 29 I ended up with someone who was about to turn 19.
Suppose mental age and this entire "I don't do this responsible adult schtick" are part of this as well.
For a reference; the woman I dated when I was 18, worked out fine, until she started pushing the late 20's and clearly become more of a responsible adult. That's where cracks where showing in our relationship. As much as I might aspire a career, I don't really have any socially accepted career plans; I mean, I could totally do the musician/writer/artist career thing, which is something plenty of adults wouldn't want since that have all kinds of things in their life they want; a house, kids, a stable income... I don't want any of that (granted, a stable income is nice; but the circus and jumping through proverbial hoops required for it, are not IMO).
So yeah...
As I'm browsing OkCupid and similar sites, I tried to make an effort to look at people my age, but I have nothing in common with most of them at all. Mostly because of the aforementioned "stable career" thing. And even there, I connect to people still in their early 20's. And as much as I don't care much for age, it's not just me. Obviously other people see age, and not everyone considers it "just a number".
I was talking about this with a friend of mine the other day; age gaps don't seem that odd the older you get. An example he told me about was years ago when he was at the gym and a girl started talking to him. He was 22 at the time and someone commented if they were trying to set up a date or anything. My friend commented "nah... she's way too young". To where she, a Brazillian girl, commented; I'm 15, but in my culture it's perfectly acceptable. So 1. it's a cultural thing in some parts (not to mention a question of legality). and 2. 7 years... 22 vs. 15, sounds odd. If you're 32 and 25 it's not that odd (or 42 and 35 even). The other way, it gets a bit weirder I suppose; 18 vs. 11. 15 vs. 8 and so on.
