This book will change your life… The let them theory by Mel Robbins. ...

Rule number one in the let them theory is that human beings only change when they feel like it. And you will never be able to change another human being. And the single biggest mistake that I see with anybody dating or anybody in a relationship is that you're holding on to the potential and you're living in a fantasy in your head and you're not accepting reality, which is why you need to let them be who they are and then decide what you're going to do about it.
