I think you're mourning what could have been and that's perfectly normal. I have RA and because of meds I could not have the 3rd I've always wanted. (Nevermind it took 9 1/2 yrs to conceive) Eventhough I had 2 and love them dearly I felt horrible that I could not have a 3rd. I feel like I let my DH down, and my kids down. I know in my heart it was the right decision. My health has greatly declined in the 12 years that I have been diagnosed and my meds have increased. I'm sure your DH is thinking long term. What if he can not physically help you in the future, what if you have to care for for him and them, what if he has to go out on disablility and your income is cut? These are all questions I wrestled with everyday. I am sure this goes through his mind daily.
I think you have every right to feel bad and grieve and don't feel guilty. Here's some
to help you get through this. 
We do know what you're feeling.
