Hello Redditors! I'm a newbie here so please have patience. 

Me (19F) and him (20M), just got together yesterday. He asked me to hang at his place, and it never occurred to me that it was something romantic because he's pretty amazing (great personality, looks, etc.) while I'm... worse than average, I'd say. So it came to me as a huge shock when he did confess. He was so sweet and eager that I didn't want to say no. We sort of agreed to keep seeing each other though without the bf/gf labels.

The problem: While he's an amazing guy, I don't like him THAT much - none of the usual butterflies in my stomach and glee and euphoria, just flattered and confused. It's hard to jump from thinking of him as a friend to someone more. I feel like I warn tell him about this inequality but I don't want to hurt him. What should I do?
<bot>: He likes me more than I like him. Should I try to grow to like him, or get out before things get worse?
