Need advice

The guy I used to see had found out I was pregnant and he is pressuring me into having an abortion because he’s on the “ possibility of being a dad” he said If I did it I would make his life better he said even if I’m with someone and he could be the dad he still wants me to get the abortion to ease his mind. The abortion was never in my plan but I just don’t know how to feel about all of this. It’s my first pregnancy
