I’m pregnant

My baby is currently no bigger than like a pea or something and right from the start I always said to myself no matter how old i am when i get pregnant I’d never have an abortion but my baby daddy is 19 and doesn’t want to keep the baby. I’m only 17 and he says he wants to be able to say he’s ready for it but when are you ever ready to have a baby? He says if i keep it he’ll leave me because his family and friends wouldn’t want anything to do with him if he’s a dad at a young age but I don’t want to have to terminate our baby all because he’s not ready. Although the baby is as much his as it is mine, the females in my family all struggle to conceive and have life threatening problems if they were to go through child birth and it feels wrong to be blessed and have my baby daddy want me to get it aborted. Can I have some advice? Do you guys do okay at being a single parent? Any advice in general for a new mum?
