Jordan, I forgot to say in my last post that if he is "being a good sport" about you eating in front of him, I think you should. Mainly because if he is likely to never eat normally again, and he wants to attend social things where normal people are eating, he has to get used to watching other people eating, and talking, enjoying thgeir company, etc. without going crazy because he can't eat. You are the person he needs to practice this with.
I personally find it really hard when friends say they feel bad eating in front of me even when I'm saying I'm fine with it. If I say I'm fine with it, I'm fine with it, and I want the socail interaction that comes around eating together. I once arranged to meet a friend for lunch at a restuarant she loves in my town (and I used to love when I could eat) and told her I'd just sip on coffee while she ate. I made sure I fed myself a couple of cans of jevity before going ebcause it's mostly only hard for me to wacth others eating when I'm hungry and when I got there (on time) I found out she had gotten there early deliberately because she didn't want to eat in front of me (so she was already on the end of her meal)! But then we didn't have as much time to talk (it was winter and not a nice day for just walking around outside). And I didn't get to smell all the good food smells. I kind of felt robbed even though she thought she was doing something considerate.
Give your husband the choice of joining you while you eat or not. Tell him it's fine if suddenly it gets to be too much and he has to leave. But take him at his word that it might be OK because I think otherwise you may be unwittingly making things harder for him.
