Adoption

I'mconsidering adoption because well I don't trust the father. He's a druggie. When we get is a disagreement he leaves and we don't talk or see each other for usually a week, and drinks and does drugs. I'm 17 years old and scared I won't be able to give the baby what it needs or deserves. The baby deserves a stable family. I'm sort of at war with myself. Any input?
