Why is my ex flaunting her new relationship on social media?

My ex and I broke up and we still follow each other. Lately she will post pictures of her out in hotels and put captions like “when you meet someone who truly has a lot in common” and “I’ve been so social lately I’m starting to get burned out” is this just her living her life or is this to make me jealous?
