I am glad that you are not giving up. Instead, looking at other options. Yes, there are some people who want biologically related children. Your husband is one of them. For some people, it is very difficult to show love and affection to children that are not related to you. Maybe, that's why your husband doesn't want adoption. You can go for surrogacy. I went for it too. Last year, I was diagnosed with cancer. I had to undergo a hysterectomy. The surgery removed cancer. But, it left me infertile. I could not conceive. My husband found out about a clinic in Europe. We had to shift here to visit the clinic. We went through the process. Finally, I will be a mother of a pair of twins soon.
