24 year old man engaged to a "CF'er"
If you think that the relationship is to much of a strain then you should probably think about the future. What if her health gets better or worse, what about if you can or can't have kids? Would you still be in there for the long haul. You should sit down with your fiance and discuss these things. Also think about the amount of stress on your body so go see your doctor. Also the money it takes to support a healthy CFer let alone a sick one is a lot. The meds, food, hospital stays, and anything else is really expensive.
P.S. I hope this helps you.
