It isnt enough to love someone.To remember yourself in the relationship, you have to love not only them but what they bring to your life. You have to love who you become loving them. Love will change you, if the change that comes makes us ugly, then turn away from it and let it go away to someone else.
Love should cause you to bloom, cause you to become more beautiful, more fulfilled and capable of going beyond yourself. If you find yourself with less, find yourself with more sadness than joy, You need to turn away from this love, it isnt for you. Being free leaves you open for new discoveries. Be free and open and turn true to yourself and your own needs, never someone else.
