You are not the bad guy.
Being a parent means making tough decisions in the best interest of your child. These decisions may be the lesser of two evils - growing up in a single parent home with a loving, caring mother vs. growing up in a 2 parent household with an emotionally distracted mother and an alcoholic father in your face.
How can you watch a 16 month old baby and keep her away from danger when there is a beer growing out of your hand?
How is a toddler going to get all the nutrition she needs for brain health and body health if all she eats is apple sauce and cheerios?
Seriously. How?
