Trying to change yourself to suit what someone wants you to be or to what he/she have in mind for their selfish reasons, will definitely give the person another good reason to walk away from you the moment they find someone else who they are trying to make you a replica of.

Adjusting ourselves to become the best in relationship can't be ignored, but if it's something we are coerced to do, then, we'll be living a fake life trying to fit in where who we really are isn't sincerely appreciated.

Be yourself!
Keep growing!
Love is not selfish!
