<human>: Can you succinctly summarize the text in 1-3 sentences?

So yeah. That. We've been together for a long time now and really haven't had any relationship problems even now. I guess I just wanted some commentary/advice on how to nurture this.

It started the summer before my junior year and her freshman year. Long story short: we worked at the same place, a temporary summer job. I rigged a bunch of shifts to be with her after the first one (stalkerish, I know). Eventually I asked her out and she said yes. I know what a lot of people may think up until this point: 2 years older may be too much, it may not last, etc.

Fast forward about 3 years, here we are, with her about to enter her senior year and me about to go to my sophomore year of college. We live in the same city btw and I go to a college in the same city. 

In the past year I became a little bit more needy than usual and I expressed this to her. She told me she understood how I felt and that she honestly was giving me all the time she coyld. She has an extraordinarily busy schedule. 

We ended up resolving that problem because we agreed that our happiness was not contingent on the presence of the other at all times. We agreed that we would find ways to be happy even when the other wasn't around. This helped immensely. We're still going strong.

Now, here comes stuff we've been talking about. 

Preface: we have gone no further than 3rd base and thus have never had sex. We talk about it a lot though. She has expressed repeatedly that she refuses to even consider it at least until she graduates.

So I guess what I'm asking here is....what now? Where should I go from here? How do I help nurture a relationship like this? Feel free to ask any questions. You won't offend me with any questions at all. The only advice I will ignore is to break up, because I see no need for it.

Thanks for reading!
<bot>: GF of 3 years, I'm a sophomore in college and she's a senior in high school. Wondering how I can simply nurture a relationship with her.
