"You may have heard the oft repeated advice, “Follow your heart.” But Proverbs 28:26 states: “He that is trusting in his own heart is stupid.” Why? Because “the heart is more treacherous than anything else and is desperate.” (Jeremiah 17:9; Numbers 15:39) To be treacherous is to be disloyal or false or to be a double-crosser. Would you trust a person who is known as a deceiver and a traitor? Our figurative heart can be devious. Thus, a relationship is not necessarily healthy just because it feels right." - Young People Ask "Why Am I Drawn to the Wrong People"
There are many more references to the heart being treachorous, but thats an example of their stance on "follow your heart". I think I've mainly seen it (as I said before) in YPA articles and articles specifically for the younger people.
