single mom to be

Me and baby's father just "hooked up " with protection but the condom got stuck inside me and we didn't notice 🙄we still talk to each other . he doesn't know im pregnant yet , im going to the clinic to get it confirmed soon ...we aren't in a relationship and i don't see my self with him long term I've always been responsible i feel like i have failed myself getting pregnant and not loving  my baby's dad. I just don't know how to tell him neither of us planned a baby in our future but i just don't know a way to tell him without being rude i don't want to be a bitch and give the wrong impression i dont want him to think im gonna be a crazy phsyco baby momma😒
