<human>: Give me a shortened version of the text

I've been wondering about this for a while, and I think I need some advice from an outside source.

Me and boyfriend have had a lovely relationship for a long time for two teenagers (1/8 of my life!). However, there have been problems cropping up for a while.

We have relationship of mutual respect and love. He's helped me combat my ADHD, where I have helped him through anxiety and depression.  While I would never dream about cheating on him, as a young person delving into a fairly serious relationship I can't help but wonder what I'm missing. We are so stable that it's hard to imagine breaking up, but I wonder if that's what needs to be done. I find myself often thinking about other people romantically and sexually. While I'm almost never bored when we are together, we can generally only see each other once a week aside from school, and I find myself yearning to experience something new with someone else. He has never been anything but kind to me, and I don't want to hurt him or throw away our relationship, but I simply don't know if it's worth it when I am always going to be wondering what else is out there. College is at the moment, a far away concern, but at that point a break up would be inevitable in my opinion. 

Maybe if it's relevant, I am also bisexual, and have never had a chance to explore that side of myself. He's on a month and a half long vacation in Europe, so I won't be seeing him for a while, which is why I've taken the time to explore the status of our relationship. Somewhat of a secondary problem, his mother happens to be my Spanish teacher and will be teaching me all of next year, so that relationship also requires navigation (I am very close with her). So what do you think Reddit? Is commitment like mine foolish when you are so young? Should I break up with him?

Honesty and kindness are very appreciated.
<bot>: My boyfriend and I are young and it's getting serious and that scares me (I think it's a little boring, to tell you the truth.)
