hmm maybe they haven't had much contact at all? like, she's definitely still creeping on his social media so she knows what he's been up to but he doesn't realize she's doing it (unless she accidentally likes a picture on instagram or something and quickly unlikes it even though he probably got the notification). but we could always have them awkwardly run into each other in the future which can mark their first interaction since? that's if he's not really ghosting her anymore
