You have been given some great advice and it sounds like you know in your heart what you want. I know myself that I could never abort in that situation, its just not for me. I would end up resenting a partner for giving me no option which would likely be the end of the relationship. That being said, he may come around to the idea. It is a hard thing to process when it changes your life plans so completely and guys seem to be more disconnected to the pregnancies in the early days in general (obviously with some exceptions). You have your family's support so you will be able to do it. It is definitely rewarding.
