pregnancy shock

Unexpected pregnancy

I am going to be a single mom. The father and I have had this "relationship" for 2 1/2 years but no commitment from him. When I told him he was very calm and even when i gave him the option of having nothing to do with either me or the baby he chose to be involved. A couple weeks later he wanted to talk about going a different route and wanted me to consider abortion. I told him that is not an option for me. I know he is scared and overwhelmed. I'm not sure how I should handle things with him. If i just need to give him time. If there is anything i can say or do to help him through this.  Any suggestions would be appreciated.
