I also have been buying courses/reading books for about 15 years. Your logic is alittle off. Positive visualization is not an exact science. I'm been visualizing winning the lottery for 10 years and I haven't won yet. If it was an exact science, everyone who plays the lottery would all visualize and win, every time! You can visualize a good marriage, but the picture in your mind can't control someone else's behavior. If that were the case, I would just visualize my teenagers cleaning their rooms or doing their homework and they would do it! I sympathize with you. During my first marriage, my spouse cheated with several of my friends and co-workers. We have kids and it has been a nightmare ever since I found out. Your goal should be to move on and try to recover as best you can. I would recommend a book to you "Getting the Love You Want" by Harville Hendrix. It is the best book on relationships that I have ever read. It will give you some insights about how and why your relationships work. When I look back, I've often wondered how much time and money I may have wasted on courses and book that haven't really worked. Then I think that maybe my life would have been worse if I didn't take the course! Keep at it and the best of luck to you!
