Alsa, This is heartbreaking on how your husband is divorcing you. Well, about the alternatives, yes, you must try for alternatives. Have you considered seeing a good RE? Actually, I am also 43, but IVF failed in my case. moreover, at this age, the success rate is very low at this age the ovarian reserve becomes very low for most of the woman. As my love ovarian reserve hurdled my fertility. Therefore, due to the age factor doctors recommended me to go for surrogacy at a facility in a European clinic. They are the most dedicated and cooperative staff I have come across. If you are interested in getting to know the details. Kindly pm me for details. And remember, nobody, is worth your love only who stand by you at your darkest moments.
