Where can I find out more information?

Where can I find out more information about divorce? I think my husband is cheating on me, and if this is the case I no longer want to stay married to him, I want to divorce him and get as much as I can of his money to punish him for not being faithful. Can anyone recommend a good divorce book or website I can check out to find out more about my options? I need a good lawyer too, though I can’t afford a really expensive one. I will have to check out my options and see if any of my friends can help me out.
