Best Friend and Pregnancy

 So my best friend is pregnant with her first baby, and I am super excited for her and her husband but I am slightly jealous. Is that wrong?  I never thought that I would want children, now I think I most definitely do.  At 32 I have decided that I want children.  How crazy is that?   But there is only one problem that I am having.  I want to start a family but my hubby has better things to do with his time and feels a family would burden him.  How do you go about this situation, with out a nasty fight or ending in a bad situation.  I have no clue, but dang I am ready already!!!
