Hi:
If you do not love the guy do not marry him.
Have you thought of adoption? Most states have open adoptions now which means that you would have the opportunity to have a relationship with your child if you wish and you would get to choose the adoptive parents as well.
Here is a link for more information: http://www.adoptionservices.org/adoption/adoption_agencies_nevada.htm
Jeff S. www.catholicxjw.com P.S. As someone who knows an abortion survivor, I can tell you right now that you did the right thing in not having the abortion. Abortion not only kills the child, it also does terrible violence to women both physically and mentally. You are doing the right thing in having your child.
