If you're looking for a book that will help you with your jealosy, may I recommend "The Feeling Good Handbook" -- it's a hands-on, well-written book that makes you feel as if the author is really talking you through the exercises. You MUST do the exercises, write them down and really search your soul, for them to help. But in the 6 weeks or so that I've been working on that book, my husband and friends have commented many times that I've grown so much already! I feel so FREE -- free to be me, do what I want to do and stop worrying about what my husband is doing all the time. As a result, we've grown closer because I'm not always there, I have my own life again and we're both so much happier for it!
I'm not saying this book is a cure-all, but it has helped me a lot. And best of all, it's only about $20! I do suggest seeing a therapist, too, but as support more than treatment. My therapist is cool, but she's not nearly as effective as the work I've done with that book!
Good luck -- we're all in this together!!!
