I think OP, you should be highly concerned that this man does not want children - ever.
For him to be so cold hearted, and think of everything purely from a financial viewpoint demonstrates how anti-children he is at this point in time. Will this change over time, or will there always be a new financial goal to reach?
Please stop asking friends and family members to add their two cents on what you should do. It's not their pregnancy and they should not have any say in what you do with your body.
