<human>: Summarize the given text in a few sentences.

Before I explain, keep in mind I'm not the best at writing so it might be a little confusing.

Me and my girlfriend, Lindsey, have been dating for a while now. It's been hard, we've been through a lot together, but we're still together today, happily.

I know the whole "you're kids, you have your whole lives ahead of you and what you want now is completely different from what you'll want 5 years from now" thing. I know I'm young, but regardless of my age, I wanna know if it's really a possibility. What are the pros and cons of dating my "high school lover"?

There's a lot of background here that I don't think is necessary to share because of the question, but if you'd like to know anything feel free to ask. I wanna know everything I can that'll help us last as long as we can.
<bot>: As the title says, how likely is it that I'll be with my girlfriend forever/marry her and have children with her?
