I need some advice. I'm a terrible husband what should I do to fix it?
What makes you a terrible husband?
I can't support my wife, she has no money and I'm not fully committed to the marriage.
It's good you acknowledge your flaws as a husband. You shouldn't be a terrible partner though. Maybe you can talk to your wife and identify areas you need to work on to be a better partner.
I can't take the stress anymore. I want out of this marriage.
Maybe you can find a way to work on your problems together. There has to be a reason you fell in love it's good to try to fix it.
