Should I get the abortion he so badly wants or should I follow my heart by not doing this?

Me and my boyfriend have been together for almost 3 years. We both found out together that I am indeed with child. I went for the first sonar yesterday and baby is already 16 weeks old. I have already grown to the child but all he sees as an option is aborting the child and he is very supportive of me in his decision. I had an emotional break down last night telling him that I cant go through with it. Our parents dont know neither does anyone else. He is a full time student and my work is all about traveling and Im only home about 6 days a month... If I keep the child it means ruining his life and losing him and of course getting a new job. Please be open minded when answering.
