Xeromag is a totally awesome site with loads of info & quite often he puts a humorous twist on things to help alleviate pressure and make us laugh
The Misanthrope site is good too. She has lots of good advice but with a snarky attitude rather than a humorous one.
Both of them will suggest talking to your wife about how you're feeling. Use 'I' statements rather than accusatory 'you' statements. (I feel this way rather than You made me feel this way).
Stop blaming yourself & don't blame her.
