Hi coffeegirl,
No two people are alike. Be it men or women. We all handle things different in our own way. Which is good and bad.

I think it would be great if he would drive you, but since he is not, I vote to take public transportation. Like car service, or a taxi.

Even call a friend, and offer lunch to that person. Going to MRI's is not a big thing, if you are able to, but when you have Vertigo or dizzy and nauseas, then I think your husband should drive you.

So let him pay for it in cash. Good luck to you.
