As someone who has struggled with infertility for several years, I can tell you that what you have is a gift and one not to be taken lightly. Keeping it should be obvious. At the very end of this, it's not about your boyfriend. It's not even about you. You have a life inside of you that needs to be protected at all cost. You need to do what you have to do to make sure the life continues. If you aren't ready to be a mother, and if your boyfriend doesn't want you to keep it, then there is always adoption. In fact, you can get medical and financial support from adoptive families through your pregnancy. If you don't care what he thinks (or your family), then there are Christian programs that help women in your situation (crisis pregnancy centers). They can help with prenatal care, as well as supplies for the baby after you deliver.
