My babies dad has been nothing but selfish! He claims he needs his money for the movie suicide squad when his daughter needs diapers. and he thinks it's okay to only spend 1 day out of the qhole month with his daughter and spends the rest with friends because he's stressed. Somehow I feel like he doesn't want the responsibilities of his kid? Am I overreacting?
