I'm going to secretly get an abortion. Will God hate me?

I just found out today I'm pregnant. I'm just not fit for motherhood and would be a terrible mother at this stage, particularly with my full time work and the father being someone who is immature and not fit to be a parent. That's why I don't plan on telling him. I've decided to get an abortion, but will this mean that God will condemn me and despise my actions? I really need to do this but people are telling me otherwise. I just hope God will forgive me. Is abortion permissable in his eyes?
