She may be genuinely sorry for hurting your feelings, but that doesn’t change her thought process.  She only knows why you were so upset when you had to literally spell it out for her. She seems pretty oblivious to the fact that other people have feelings too, and I would be willing to bet that you will end up back in similar situations. 

And most of all, never date someone who makes you feel bad about your body. And NEVER date someone that says you shouldn’t reproduce because of your weight- not just you, but all “bigger” people.  Seriously, wtf is that. Who says that?!
