Hi Kristina. I'm probably not adding anything that wasn't already said, but I have had a lot of time lately to reflect on the sacrifices and risks we undergo for the people we love. One thing I believe strongly is that you should not feel any guilt over accepting an offer like your husband's.I also agree with your point that it is pretty scary to think of worst case outcomes. But waiting around feeling helpless is also terrible. I'm sure your husband feels compelled to help you in any way he can. You might want to let him off the hook but he's on the hook either way. You just have to reach a decision that both of you can accept.
If I lost the kidney after the transplant, how would I feel then about my husband who has given away one of his kidneys?
