Telling my boyfriend about getting a Abortion

Both of us are not financially and mentally stable to have a baby. I haven’t told him I am pregnant yet. I’m going to get an abortion because there is no way I can have a baby right now at this point in my life (20 years old) . We both still live at home there is absolutely no way we can afford this. I’m already working 2 jobs and barley can pay my own bills and car payments. I’m scared to tell my bf my decision. I’m thinking about not telling him and just doing it on my own. Any suggestions on what I should do?? I’m very confused. And we are not ready for a baby.
