Is anyone ever scared of how they're gonna raise their baby???

Me and my boyfriend were arguing about how we're gonna raise our baby & he was saying how he doesn't want the baby to turn out like him and how he did all these drugs and how his life went cause of his family.

He was saying that he's gonna let out kid drink and smoke weed (around us) cause he doesn't want he/she to do it behind our backs but I'm scared they're gonna wanna keep drinking and they're gonna mess up their body or worse.

& he told me that I'm trynna make them selfish and shit and hide stuff from them & how he doesn't want to be a strict parent but I'm so scared if he teaches them that stuff and to be okay with it they're gonna get into something and I won't be able to help them...or they will get hurt. I want them to understand that there's consequences with every action they do but with my boyfriend he's gonna tell them something else.

I need yalls help I'm so scared and paranoid for my baby's future..I only want the best for he/she.

Ps I'm only 16 and he's 17 not living together.
