Is this a red or a green flag

And she liked my post and replied to it on instant messages with a πŸ‘ this morning I sent her a flirty text 'I can't wait to see you πŸ˜‰' and she replied.'Can't wait to see you too❀️' but I've noticed when she mention a boy she likes, she never mentions it ever again. Could she been doing these just to make me jealous? WHAT DOES IT MEAN y'all I'M SO CONFUSED!! 😭

Is this a good or a bad sign and what should I do?
