She refuses to consider getting outside help, whether with him or a couple of other long term situations that are stressful.
I have been told several times to not do anything, and since I live with them and we share a car, I have to abide by that. But, letting things float is just making them worse, in my opinion.
I am concerned. If there should be a major problem (knock on wood), then it would be a mess, and they might be forced to make some changes. We're not there yet - both of them can drive, for example - but I'm someone who likes to be prepared early for the possibilities.
I have been occasionally pushing for her to attend a spouses/caregivers group, but so far no luck. What do I do?
