Jealousy or something else?

Yesterday I asked my ex girlfriend if she wanted to have dinner together (we did the week before), she said "we'll see, if I get all my running around done" well I never heard back from her... I texted her this morning and asked what happened? Said she was busy. I said thanks for letting me know... she says 🤷‍♂️ there's plenty of other girls you can have dinner with. I'm like seriously? You're gonna be like that? She says, I mean it's not a lie, I see all yours and theirs likes, posts and reactions on Facebook...
