I don't know about where you're at, but before my town had sorta proper bus lines, they had a courtesy shuttle that you could call and they'd pick you up at an arranged time and drop you off.

But honestly, I think the most immediate solution is to have a good long talk with your wife. Sometimes going to things you don't want to is just part of marriage. Bring a book or an ipod or something, Let you have some fun for a while. She needs to support your mental health, and if you're going stir crazy and she's got the literal keys to a solution, she can and should help you.
