I was outed...

Basically I was thrown into some drama between a friend (R) and someone else who knows both of us (J) and somebody outed me to J. While they were accepting I didn't intend to be out to them... So now I have to figure out who outed me so I can tell them that wasn't cool, on top of still investigating who's sending me those harassing texts (which I haven't received for a week so I think it's over).

Have any of you been outed?
