Any day gamers here? Just starting approaching and I was hoping for some advice from you guys.

Did my first approach today.. I bombed spectacularly. I went up to a girl say to Hi and that she looked nice etc. She blushed, stared a me blankly with no response, I panicked. I stuttered and stammered just to break the awkward silence. I asked what her name was, which she told me but then added that she had a "boyfriend". I left it at that as the anxiety absolutely killed me. I would appreciate any feedback from you guys.
