There are a few ways to tell if someone is ignoring your messages on Facebook Messenger. One way is to check their Facebook Messenger app and see if they have any notifications that say “Notifications turned off.” If they do, then they may be ignoring you because they are not using the messaging service as much as they should be. Another way to tell if someone is ignoring you on Facebook Messenger is to look at their profile and see if there are any changes in their profile picture or name since you last spoke to them. If there are, then it’s likely that they have been ignoring you and may not be aware of how important it is for them to keep in touch with you.
