PLEASE read and answer, I need at least a bit of advice here?

If you were a good mother, you would not have someone like that around your child. It doesn't matter if he's the dad or not. He's a druggie that doesn't come home because he's at the drug dealers house. Did he know that the baby needed food? I mean, it's one thing if the baby had food but you didn't, but if the baby had no food then that is a MAJOR problem. You need to file for full custody, get a job if you don't have one, and GROW UP. You may be only 18 years old, but you decided that you were woman enough to open your legs and have a child. Now that child should be the MOST important thing in your world. You have to protect and provide for that child. Your child's father is still a child and looks to have no desire grow up and do the right things in life. Leave him and learn to take care of yourself. Maybe when you've learned to take care of yourself and your child, someone perfect for you will come along. Until then, do what is right for your baby.
