I am sorry for your loss. It’s not your fault. Don’t bother such situations if your ex-husband left your just because of this. It’s insane. But your husband is very supportive. Choosing a surrogacy is amazing. It is the real blessing for many couples. I was also an infertile woman. I also choose surrogacy to have my baby. I went to Eastern Europe for my procedure. I will suggest you the same place for you. They offer cheap rates and quality treatment. Good luck dear.
