I'm in a relationship, but we never talk in person even though we're in the same class, and he didn't ask me out in real life either, just online.
What about this relationship makes you concerned?
I just feel like I'm not sure what I'm doing.
If you are in a relationship but you are confused about where it is going, you should sit and have a candid conversation with your partner. You won't know what's going on unless you ask, so worrying about it won't solve anything.
I may end up being disappointed.
It's better than being in a weird relationship like this. Do you want to continue being in a relationship where you are ignored by your partner?
