Will he ever forgive her
For not staying strong?
How will he live without her?
What she did was so wrong.

Katie, he has nothing to forgive. When he met you, he met the woman he loves. Children CAN enhance a marriage, and that perception of a family, but it doesn't mean it WILL. He loves you for being you, not for your ability to, or not to conceive. On the other hand, the 3rd and 4th lines, I'm not sure how to read.. without her because you may wish to conceive anyway, with the risks as high as they are..? Or without her because he won't want to go on if you can't have children..? If you go against the doctors advice, then things may still be ok.. but is it worth that risk? Is it worth giving a life when you may not be able to raise the child yourself? He is not with you so that you can provide children. Yes, he wants children, as do you, but YOU are the person he chose to spend the rest of his life with. Beyond that, if this gives you the incentive, then take it, and use it, and make the changes. Then, you will be in a healthier position to conceive, and better still, to live a longer life with your man.. Even without a child, do you want to spend the next 15 years wondering, or do you want to make the changes now, and look back in 40 years, and know that you had the best life because you had a healthy life..?
I love you, and I love the way you pour your heart onto the page, but Paul loves you more, and he loves you because you are his world. Hold onto that, and make the changes so that you can enjoy him, and your marriage. xx
