I do talk to her in portuguese! She'd probably think I'm a freak if I started talking to her in english.

And Heartlight, thank you so much for replying, but the thing is, I'm a girl too. I don't even know if she's into girls at all, that's why I'm so lost. I want to at least be friends with her if we can't be something more. But I will try to work up the courage to use one of your tips. I believe if I wasn't so shy and tried to have an actual conversation with her, she'd keep the conversation going becuase she's very friendly and outgoing and all and she seems to like to talk to me. *sighs*
Thanks again.
