It depends on how you feel about your ex and your current situation. If you've moved on completely and don't care, then do nothing. If you're still a bit emotional about it, take some time to think about why it bothered you. If you think there might be a chance for a friendly relationship, you could reach out in a non - committal way. For example, you could comment on something in their own stories or posts if they have any. But always keep in mind your own boundaries and what you want from this interaction.

It depends on how you feel about your ex. If you have completely moved on and are indifferent, then there's no need to do anything special.

This sends a clear message that if they want to be a part of your life, they need to engage with you through proper communication, not just be a silent observer of your stories.
