@moosie822,
If you was my wife my over riding concern would be your state of health not my feelings!
If you wish to talk about it I would talk to you and in fact I would wish to share in any of your ongoing treatments that the menlth health people would think would be helpful to you.
From your short posting I would suggest that both of you should be in some form of join councling.
In any case all my best to you and your husband.
