Hello, I’m just seeking advice.

I’m only 6 1/2 weeks pregnant and the baby’s dad is begging me to get an abortion. Today he randomly just sent me the money for it. I’m really scared to have an abortion cause I’ve never had one before and I just know it’s gonna mentally fuck me up. I also know that with him trying to force this on me so much, if I go through with having this baby I’m gonna have to do it alone. I’m just feeling mostly really alone and I also have a son who is 4 who I am a single parent to. But he knows the baby’s dad as his dad since he on and off helps me with son. Any advice ? Thank you in advance.
