I feel like Jamon needs to get involved here.
Thanks for the intro

So my current girlfriend and I met at the start of Year 8, started 'dating' at the end of Year 8. So we'll be celebrating our 7 year anniversary in November (we're going on a cruise, mucho excited!!). Obviously no one expected it to last as long as it has back then, and look, logically we might not have either at the start. But that's not what we were in it for, we weren't looking for a husband or wife - We liked each other. We were both into nerdy things. We made each other happy, so hey, why not?
She's a huge part of the person I've become today. All of my self confidence comes from her, a huge amount of my work ethic comes from her (hard to not study when your girlfriend is studying so hard lol) - I shudder to think where I'd be without her because I honestly attribute a vast majority of what I've accomplished in the last seven years, in some way, to her.
So yeah, I'm personally a big believer in high school relationships, it is just a part of the experience. Not that everyone should go hunting for somebody, but if the opportunity arises and you are into it, go for it! Worst case, you end up in a bit of a shitty relationship - It teaches you a bit about yourself and your wants/needs, a bit about relationships. I'd hope that usually, you have a good experience, have some fun with the person you are with for some decent period of time - And on the high statistical chance it doesn't last - Well, life goes on. Again, you learn a lot, and it sucks for a bit, but you always dust yourself off.
Or you get lucky like me, and you find who you'll end up marrying (when I save up enough for a bloody ring, lol)
