Forced abortion

So I’m a single mom still living with my parents and trying to go back to school I got pregnant by a guy that I was seeing for about a month and ever since I told him he wants me to get an abortion but I love this baby so much I want to keep it I’m good financially but this guy will not let it be he is going to actually get a lawyer for me to get the abortion because apparently I lied to him about not being able to get pregnant I really thought I couldn’t get pregnant at least not easy I’m so lost and I feel trapped what the hell can I do ?
