<human>: Can you give me the gist of the text in a nutshell?

Hey, so I guess there aren't really any huge problems atm with my relationship, but that doesn't mean that there aren't things I'm worried about.

This has been my first relationship (have been in a few) where it seems like things could last for a really long time.  We're both very open people and have been pretty solid with communication.  We've yet to have any conflict that's resulted in either of us raising our voice to one another, which I think is a great sign.  Of course, there are a multitude of things that I think make this relationship amazing, but that is beyond the point of my post.

Nonetheless, I recognize I'm really young, and I was hoping to get some advice from you much more experienced people on making it last as long as it can.  Of course I recognize that I can't just MAKE a relationship last forever, but I do think there are things that I should know and learn to give it the best possible chance.

We're both very hopeful and yet realistic about our future.  We're just trying to live in the moment with tidbits of planning in the future, but we do recognize that while we are loving our relationship at the moment, that doesn't necessarily mean things will always work out in the end.  I've read enough on /r/relationships to understand that people change over time and who we are now won't necessarily match how we are in a couple years.

Regardless, I'm just hoping to learn from any past mistakes that you guys may have made in a relationship during my age or bring a few key points to me so that I know what to expect as I grow older or maybe learn a few things that tend to cause ends to long-term relationships in general.
<bot>: Just a young lad trying to learn about what things to expect in a long term relationship as I grow older and what I can do to give that relationship the best possible chance.
