We as humans go through a lot of changes but not all is good and not all is bad! Some people change for themselves other to please someone else!
Why do people who say they love you want you to change? Who would they like for you to change into and why? If they love you why do they want you to change? How can they say they love you and then ask you to change?
When you say you love someone you love all of them not some of them! If it is just a part of them then you don’t love them at all just obsessed with that part of them not love or just pure lust.
When a person say they need to change they change something about their self that would be pleasing to them! Some even change everything from religion to what they eat, their career to lifestyle. Self preservation is your preference but when it is someone else who wants you to change and you are comfortable with yourself; it controlling! Live life for you before you can live it for another!
