<human>: Hey, all! This is my first relationship, so I don't know if what's happening is normal in long-term relationships or not. I could really use some guidance.

**A brief background**: We started dating in college but went to school in different states, so we only saw each other on weekends. She is now in grad school with 1.5 years left and lives with her parents to minimize loans. I also live with my parents while working to save money for a graduate program that I am starting next year. We currently live 20 minutes apart but still mostly see each other only on the weekends due to our busy schedules and lack of privacy.

**Current situation**: We're both feeling a little unsure about our future together. We talked about this recently but neither of us knew what to do about it. Part of what's causing us to worry is that I'm moving ~7 hours away for grad school next year. We would realistically only be able to see each other once or twice a month at best.

I can't say for certain, but I think my girlfriend is having other reservations. She alluded to it in our recent conversation without going into detail. I know I have other concerns than just the distance. Lately I've been feeling a ... curiosity ... about what else is out there in terms of dating/sex because I only have experience with this one girl. This is one of the things I don't know the normalcy of. 

We talk about the future a lot, and, while I'm happy in the here-and-now, I'm becoming increasingly unsure about our long-term compatibility. Right now I'm trying to reconcile current happiness with future uncertainty and find a balance between letting the relationship mature and not wasting our time. I know I have a tendency to live in the future, so I could use outside views to put it in perspective. Should I relax, enjoy today, and let things unfold as they may? Or should I take my worries seriously?

Give me the gist of the text in a nutshell
<bot>: While I'm happy with my relationship at the moment, I am having doubts about the future. Not sure if it's "normal" or if I should get my head in the present.
