Need advice...

So I've been hanging out with this guy for almost a year now and I just found out I'm pregnant and he is freaking out bad. Pretty much telling me this baby is going to ruin everything that neither of us is ready for it and telling me that we are both financially ready for this. He is mad that this was not planned and he says it doesn't feel right. He has a daughter that is 7 from his previous marriage but she was planned of course. He wants me to get an abortion but I just can't do that.i can't risk never having children ever again. I had an abortion when I was 19 and it was the biggest mistake of my life I constantly feel like something is missing. I never thought I could ever have kids because of that abortion so now that I am pregnant I didn't want to ever risk it. I am Gunna be 31 in less then a week so I feel like this is my only chance. I just don't know what to do or say to him anymore i am scared of doing this alone and I'm scared of loosing him he is my best friend. Any advice or encouraging words would mean a lot to me right now I'm trying to stay in good spirits for this baby I don't want to stress and loose it...😔
