I can relate to this. When you have very limited energy for socializing, it's significant to have one person with whom there is non-verbal communication and, sometimes, there's really only enough energy to be close to one person. It's not an easy thing for a relationship, and it's very far from what is the popular line of thought "I want my significant other to have a full life that I can just be a part of." I can say that time has been easier during the one relationship I've had since sick, where every day--even if symptoms were miserable--had the magic of distraction. Distraction is a brilliant thing. Yes, yes, yes. It sounds like you could be being too hard on yourself. Depends on how the person was hurt of course. I can relate to this, though it was me who was hurt by the 'healthy' person. That's another place where things seem wildly out of balance: where 'healthy' people have spent about 1 hour in their lifetime considering what is truly important to them and getting any insight into what makes them tick... while ill people often have a massive set of frustrations and limitations, but they know their heart and mind.
