Yep. I deactivated Facebook and it took a week or so to get used to not having it. I feel a lot better without it that I will probably delete it. I do want to keep messenger so that’s one of the only reasons to keep it.
True, but AFAIK, you can't keep your contacts (friends?) list when you delete the account and create a new one just on Messenger. An alternative is to deactivate the account [1] – this effectively removes your account from Facebook, but allows you to keep Messenger with all the contacts. (It probably also keeps other associated accounts, such as Instagram.) Although, it means that the moment you log into Facebook, your account comes back up, with all the relationships that were left off, tags, photos, etc.
