She's someone you like, of course you'd get that warm feeling when you're with her. Naturally you'd be jealous when she's with someone other than you, because they might be someone who could potentially "steal her away." I guess when nothing's official and out in the open jealousy is bound to happen. Take a step forward and make it obvious to her how you feel.
