unsure on what I really want..

recently found out I'm pregnant, only a few weeks so early days.. I've told the baby's dad and he's dead set on an abortion, even mentioning the idea of keeping the baby caused him to freak out ridiculously! 
I'm currently 19 and in my second year at university and will be in my third when the baby is born, I don't really know my feelings on abortion but the thought of one does make me feel uneasy and can't really picture myself going through with it.. all I can think about is the fact that my baby's dad feels like I'm ruining his life and he has no choice and of course the reaction which my family will have worries me a lot.. just feel like I need some advice really
