I agree with #5. Atleast you saw the status and can now dump them and move on..

Don't these sites select a default if you don't have one selected? It might be a bug in facebook. Try it. Go remove your status, make it hidden or whatever, then go back and don't change it, see if it changes for you. Maybe he wanted it to be visible, but forgot to update it, and it's single by default.

#7 - this is true: my friend regularly changes his housemates relationship status to "in an open relationship" for giggles. #9 - also a good point, the default is sinlge, so if all he did was enable "show my relationship status", that would have happened. The guy could also be a douchebag, but facebook status isn't something i'd recommend ending a relationship over unless you're 12, lol.

TALK TO HIM ABOUT IT. Communication. Use it.

Don't base assumptions off of what you saw on Facebook!! Definitely talk to him!

facebook only starts drama

Sounds like a cheater to me. It might be a false alarm, but he should be proud of you.

#10- the default is actually undeclared, you then manually change it to in a relationship or single.
