I'm seeing her again, and I"ll be under pressure to do something, but what?

This girl I used to (and still slightly have) a huge crush on told me not to talk to her anymore. I'm been resepcting that, but in a few weeks I'll see her again. I dpon't klnow whether to ignore her when I do or try to make conversation. Alot of our friends (both hers and mine) think it would be great for us to be together, so tey'll be kinda forcing me to talk to her. What should I do so there's not an awkward situation?
