Baby’s father has me depressed

Not sure what to do I tried reaching out to my baby’s dad to see if he wanted to be involved in the baby’s life (I told him I was pregnant about a week ago) to see if he’s changed his mind on anything and he was cursing at me and saying he didn’t want to be involved and I said ok well I’m going to put your name on the birth certificate so I can receive child support. (I wouldn’t have even wanted child support if he wanted to be involved) but he refused that. Then started cussing at me again asking me to show me the hcg “letter” my doctor gave me to confirm the pregnancy? Which they never gave me a letter they just called me with the results and he called me an idiot saying I’m lying about being pregnant which im 100% not. Now I’m really sad and don’t know what to do. I’m thinking about adoption at this point I don’t want my baby growing up wondering why his/her dad didn’t want them.
