Lisa,
My wife was not only surprised when she realized I was serious about donating to someone I'd never met, but she was flooded with a plethora of emotions and questions....what are the risks, how will OUR life change, what part does she play in all of this, she was feeling selfish for not feeling more supportive, how would this effect us economically, she was apprehensive about meeting our recipient and family and many more. Please tell your husband, all he is feeling is normal and I would certainly be willing to talk to him any time he wants on this forum. I'm willing to give him my phone number if he's rather speak in person.
His support is probably one of the most important components to your ability to donate and to recover fully so it's important for him to process his feelings and to have his questions answered. I hope all goes well for you my friend.
Scott
