My best friend me her FH when she was in high school too. They have been together exclusively since she was 15 and he was 16. They went to different colleges in two states but never had any problems. They finally got engaged last year (after she got her masters and started medical school) and are getting married this summer. She will be 25 this year so they were together about 9 years before getting engaged too. If it is meant to be, it will happen. I see nothing wrong with getting married at 23-25 years old (I'm biased- I'm 24 and have been engaged three years) as long as you are ready for it. It doesn't matter when you met as long as you are ready. I'm assuming you won't be getting married really really fast after the engagement, but either way you'll be ready when you are ready.
Good luck. I have my fingers crossed for you!
