What do you say/do when you see a chick that stopped talking to you? Im going with friends to a beach and my one friend said hes inviting her. Me and her made out a few times but nothing more.

I feel like ignoring her or saying hey who are you like reintroducing myself. It sounds funny but it seems dumb also if it was only like 2 months ago.

By the way im new here so this is probably beta BS. Help me out please.
