Is there an "imbalance" in our relationship?

It’s definitely the latter. I’ve talked to him about it, he doesn’t see any problem with it. In his eyes, he prefers my company to others and enjoys bringing me along. Obviously, this makes me quite happy, but on the other hand I feel that “uncomfortable” feeling. You’re right though, I am tormenting myself with a non-problem.

I think I’m a little scared that in the future, he will eventually see me as something that’s just always “there” or around like a chore. Our relationship has lasted a lot longer than most our age so I am absolutely terrified he will get bored of me one day though I’m not sure if this has anything to do with the “uncomfortable” feeling.

Lots of relationships sooner or later come to an end (or a change in their nature) for one reason or another; especially relationships between people as young as you are. Obsessing over your scary fantasies about what might happen someday can be self-fulfilling, but you don’t have to live in them now. They are, after all, just fantasies. Focus on enjoying what you’ve got, deepening and building on it.
