Am I wrong if I confront someone who's been talking shit behind my back even though a friend told me not to?

I was friends with both. one friend-- we will call her Regina-- told me that the other friend-- we will call her Priscilla-- was talking shit about me behind my back. Regina told me not to confront her because doing so would mean Priscilla would know Regina ratted on her. But i was so mad and upset at this news that i went ahead and confronted Priscilla anyways.

now both of them are mad at me. But i don't care about Priscilla... but do care about Regina... Am i wrong for confronting Priscilla even though Regina told me not to?

What would you do if you were in my shoes?
