Why did she hold eye contact with me?

I was at a party recently and there was this girl there I have a huge crush on. She caught me staring at her across the room. But instead of breaking eye contact she kept staring at me. I was freaked out and looked away thinking that she might have taken me as a creep, but when I looked back some three seconds back, she was still staring at me. What does that mean Because she has been showing some signs of interest in me lately but I never responded showing my interest in her.

Did she think I as a creep or was she showing interest?
