It should (and maybe will, someday) be clear to your husband that the one who is REALLY supplying the unconditional love is YOU, dear lady!

I can't imagine being in your shoes, but I CAN say that I'm impressed with your demeanor, your patience and your pesistence......... Now, exactly what is it that REAL LOVE is supposed to do to a person?  Sounds like you are the one "experiencing" real love, to me!

Chin up!  You are doing well, IMHO
