Yes, you should probably stay away from other women for now. It's nice to feel that someone found you attractive, but it's likely you are not ready yet. Getting into something would not be good for you or the new lady, most likely, so hold off until you are sure you are through with your wife. It's easy to rush into a new R to feel good about ourselves, have someone to share our lives with, etc. but those good feelings are likely to be temporary. That's my guess, anyway. Susan Anderson's work on abandonment warns of avoiding either extreme: rushing too quickly creates one set of problems, but never trusting love again for fear of being abandoned again is also not the answer. When the "right" time is something only you will know, but I am convinced we can't look until we are sure things are over.
Work on yourself. Use this trial as a chance to learn about yourself, love, and life in general. If you do, you will feel good overall despite having rough days I suppose we will take some pain from our failed M to our graves, but I have seen over the past year how the pain does lessen. If you come through this ordeal wiser about yourself and what you can do better in your daily life (both with the person you love and all others as well) you will find a richer, happier existence awaits. I feel this in my own situation. So many things look so different to me know, that I can sincerely say I would not trade this experience, even the pain, for going back to the old me. If I have to lose my W to gain this, so be it. The quality of our relationships depend to a great deal on self-awareness about who we are, how we got here, and what we really want out of life. So many of us,myself included, were/are on auto-pilot, unaware of how our deep issues from childhood affect us as adults. We prefer to blame our spouses, bosses, life in general, etc. for many things we create unconsciously. Keep working on becoming more conscious. Someone on these boards has a wonderful quote at the end of each of their posts; I forget who said it but the basic point is that the purpose of life is to become aware, blissfully aware.
