I'm going to sound preachy, but this caregiving is NOT your job. You are not his wife. I mentioned earlier I did that for two years for a man who was in constant contact with his ex's. I thought, like you, I couldn't be the woman who abandoned a sick man. Now, years past this, I look back and shake my head at WHY I hung in there for so long, wasting my valuable time to a man who had no emotional integrity.

It actually sounds like you want this role of caregiver to a thankless partner. If that is the case, go for it.
