<human>: My SO and I met online 1 year ago, and we instantly clicked. We were good friends for months before we decided to get serious, and talked constantly, sometimes for 8 hours non-stop. She is my first, and only, and it makes me question whether it will last; and ultimately, if she really could be the one?

I can't stop thinking about her, and all I want to do is just be with her. I've tried to think of every reason not to be with her, but I couldn't think of any reason at all. We both have agreed on our boundaries, and haven't had any issues. We never fight, and we are very open to each other. 

She's the only person who I have really opened up to; or for that matter, the only person who I enjoy being around and talking to. She really seems like someone who I could spend the rest of my life with. But what makes me question all of this, is the fact that she is the first person I've dated. I know I'm a just a young guy who is all full of hormones; and I have absolutely no clue what to do, but to rely on my instincts. I'm so confused.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: She's my first GF, and we never fight. Long distance hurts, but I'm young and confused. How can I tell if this is a meaningful relationship that could go onto something more...?
