If it is the other who validates you, who gives meaning to your life or your reason for existing; if the other is your world and happiness, your sun and the air you breathe, then… who are you? 
You are an appendage, an extension, an accessory, a puppet, a stick figure, a love beggar. 
You depend so much on the other that you do circuses, maroma and theater to keep him happy and not abandon you. 
If you need him, then you cannot be yourself: you beat around the bush, you are diplomatic, you walk on tiptoe and take care of each one of the things you do, say, think and feel so that the other is not going to bother you. 
You do everything to please him at the cost of anything, your dignity, your integrity and at the cost of yourself.
That's why...
