Oh Melissa! I can't even imagine how hard it must be to live every day knowing that you are losing the person you love most in the world! It is just heartbreaking. No matter how much he tries to plan the future to ease that for you he cannot take away your loss of him. It is bringing tears to my eyes. You guys clearly love each other very much and for that you are lucky. Not everyone out there gets to have what you guys do.
As far as the hospice.... from what my mom told me and what I saw with her bf's passing the nurses were tremendously helpful and supportive. They came everyday and took care of him so he could pass at home the way that they wanted him to. They helped to manage the pain and keep him as comfortable as possible. They also set my mom with help as it was really hard on her. I'm sure you both can expect the same.
Keep being brave!
