Congrats and best of luck with it all Talia/Carmen (?).
My 'hubby' (we are not married per se, but defacto, and it's just easier to say hubby coz he basically is,) had a vasectomy over 10 years ago too.
I knew that he had been 'fixed' when I met him but that didn't change the way I felt. We want to have kids together eventually but since finding out that I have PCOS and a septate uterus it seems that we would be better putting our money into IVF instead of a reversal.
Good luck with shedding the weight you want and I hope everything goes smoothly for you and your husband.
When I am thin, fat will be in!
