Toni, it is good to hear from you! I hope the problems with the prospective in-laws work out. I can understand their concerns, but they do need to be educated. Also, I think for persons with liver disease, it's a case of grab happiness where you can find it. It helps one deal with what's ahead. I hope the fiancee is very supportive of Will and also a positive, upbeat person.
Regarding Will's weight loss, perhaps he could get a prescription for an appetite booster? I know there are drugs that will enhance appetite...just can't recall the names at the moment. Also, Ensure or Boost would help get some calories and vitamins/minerals in him. I personally use Slim Fast when I'm unable to eat. It has about the same amount of nutrition as the other supplements, just less calories...and I think it tastes a whole lot better. Carnation Instant Breakfast is another idea.
Everyone I know with severe liver disease has problems with swelling/ascites. Is Will on any diuretics? I am on Lasix and Aldactone, which has helped a lot, but I still get a little swelling around my ankles at times. Will should be minimizing his salt intake, as it causes water retention. That means no chips, salted nuts, or added salt in the diet. Also, he should be aware of all the salt in canned and packaged foods, particularly frozen dinners and soups, and condiments such as pickles and olives. I know I've become a chronic label reader, and mostly eat fresh fruits and vegetables.
Take care, good luck with the hearing, and please keep us updated when you get the chance!
