Met a girl at a party, Do I keep talking to her?

I met a girl who goes to my school, I knew her before, we'd exchange smiles in the corridors, occasionally have conversations, Just mutual friends, But I'd had a slight crush on her for a while, I digress, On Saturday at a party we spent alot of the time together, and hugged and danced (No kissing or contact) So now I haven't talked to her yet, And I'm not sure if she'd want to hear from me, I don't want her to regret talking to me or anything - >
