Pro-Birth vs Pro-Abortion

I need some support and advice. I am 4 weeks and 4 days pregnant. The guy I have been seeing since Oct recently told me he isn't ready to be in a committed relationship. A couple weeks later is when I found out that I am pregnant. He sees and voices all the reasons why we can't and why we shouldn't have this child while I see all the reasons why we can and why we should. This isn't the way I planned on having my first baby and I agree with a lot of his reasonings but I am lost and stressed on what to do. I love the idea of having this baby. I know that if I had to I could do it on my own. I guess I just need some advice. Please help me.
