Facebook, I will say, quite honestly, CANNOT f' up anyone's relationship. It just is there. It's an application for cripes sake! What you did with it, how you use it is up to you and it has no power over you or anyone's lives. that's just silly.

People need to have the control and ability in themselves to know whether or not they can handle looking at fb and not getting all personal on it with people.

Just. Don't. Do. it.

People that post crap, their complaints, their daily drivel about life as if everyone in the world wants to see it, are just asking for trouble, and I don't want to see it, so for myself, I just turn off their posts showing up in my newsfeed automatically.

Is a friend annoyngly an over poster? what can you do? besides unfriending them which in and of itself is a huge drama invitation?

1. unsubscribe or choose their profile, go to where it says "friends" and on the dropdown, uncheck 'show in newsfeed' this will turn off the automated posts to your newsfeed so you can choose when and if you want to see their posts.
2. if necessary, turn off notifications also (same method as above but uncheck "notifications")
3. Chat - turn off chat for those that badger or hit you up too often when you dont' want them to. You can choose to turn off chat altogether, choose to turn it on for only a select few or make selections as to who you do not want to chat with.

In drastic situations, unfriend them and if necessary, block them.

If none of these things is enough to keep you from allowing FB to "ruin" your life, perhaps it is indeed time to get off FB.

All in all though, FB does nothing to relationships. people ruin them. Maybe its' based on something you saw on facebook or something you posted but frankly it did not do it on it's own.
