It depend on the whole situation. It depend on how he take the break-ups... if he is going to stalk you then it good idea to unfriend him. If he is not that low to stalk you and respect the breakups and you both decided to stay friends then why you want to unfriend him? Sadly most breakups didn't go well.
You can refriend him later when you are ready.

If we ended on good terms and remained as friends then pm Facebook I would just block all posts of him from appearing on my newsfeed rather than blocking his profile. On snapchat I would just leave it and I don't have ig so I don't know what I would do there 🤔
