I’m currently 17 weeks pregnant and trying to decide on a baby name (which last name to use)

I’m no longer dating the baby’s father and our child will end up having two first names if I use his last name. He asked me if we can use his moms maiden name buttttttttt I kinda don’t wanna 🙊

The names we have picked out would go well with his moms maiden name but he constantly makes hints that he doesn’t wanna be in the child’s life. He’s just staying for now because he doesn’t wanna be put on child support. I feel like my child would wonder why it’s last name is different from mine and it could possibly cause a heart break when he ends up walking away 😢

Am I wrong/selfish for wanting giving our child my last name? 🤦🏻‍♀️🤷🏻‍♀️
