Hi, Manuelito. Welcome to PC. After years of marriage to your ex, your mind appears to be conditioned to expect the worst even from normal situations. Maybe you can change this conditioning gradually by remembering to tell yourself (write it down on a piece of paper and refer to it as needed) that your new wife and your ex are NOT the same person and that these feelings are no longer relevant. These feelings are more than in your mind, they are in your muscles and bones! It will take time and effort to re-condition yourself. Seeing a therapist will help as you need to talk about it. Don't fear therapy; it can help you. It does not mean that you are really sick, just that you have a conditioning problem from years of a bad marriage. You need to talk those feelings out of your mind and your body. It is possible to recover from your past marriage and make your new one better than it is now because you will be healthier and able to enjoy it more. Here's wishing you all the best.
