My ex played this game on me for months when when he started his devalue phase. I was soooo lost on how to respond so the pick me old me stayed and tried everything to become someone he wanted. The hard truth that I learned was that he would never know what he wanted.

This is a way for a them to confuse you, keep you around as a back up in case whatever they are looking for (which will never be found) doesn't work out, and to manipulate you, to control you and to abuse you.

So if a guy claims they don't know what they want then gladly walk away, don't ever look back and find someone who definitely knows they want you.
