How did I get here?

The past year I have been spending my time and money taking care of my body in hopes that it would improve my egg quality and we would have our own little miracle. I can't believe I am ready to give this up but it has felt so good to be a normal person and not worrying what I am putting into my body as much as before. So, after 2 failed IVFs with my eggs I am ready to move onto donor eggs. Sometimes I am super excited and other times I feel like a failure. Why would a man want a women who can't have bio children?
