Terminal diagnosis has caused irrational behavior

I'm exhausted and at my end.  My husband was diagnosed with Renal Cell three years ago.  I was unemployed at the time and he was working.  We juiced daily and after 7 mo this of chemo he beat it.  I was working three jobs by this time and he was unemployed.  In the following 21/2 years, it came back with a vengeance.  No one wins against renal cell.  I have busted my butt for years keeping him going, supporting, all of it while he battles to live.  

 

By some miracle, after 14 months of super chemo that ravaged his body, he has beat it down from stage four and the doctors are telling us remission in two months.  The doctors don't know how...other than the juicing and hard work we both have put in.  I was completely elated!!  I mean I get to keep him for a few more years most likely.  This could not be better news.  All the suffering on his part, and me with three jobs and coming home and caring for him every other second it all paid off.  Right.?.

 

So now I'm not sure how to say it, but just say it.  My husband now tells me.  I only got 2 to 3 years left on this planet and I want to experience all the things that are taboo and really live the last few years.  I'm thinking what..pot...travel...seeing family and amazing places.

 

 Let's just say that is not what I heard.  At what point does his adventure and my boundaries of what is acceptable end.  I am disgusted with some of what he wants to do and not sure I can support it
