How do you handle it when it's on His end?

It's sooo hard. I know I do my best not to put the blame on him but what else can you do besides supplements on his end? He works out of town alot so trying to get him to accompany me for one of the tests where I need a driver is out of the question. And unfortunately, no one else can do it. Bc no one knows our issue. I'm thinking I'll just have to suck it up and get a taxi ride.
