Sunny, I wouldn't consider dating until you are divorced. Why? Because she could turn around and use your dating as adultery in her case. Most lawyers will advise you not to do it until the ink is dry on the decree. I know...she's most likely doing it herself, but you aren't dealing with a full deck here. Also, if you start dating, you will be sending her a clear message that it's okay for her to do it and it will alleviate some of her guilt.
My advice, hang w/your friends or if you absolutely need female companionship, do it in a group setting for now. However, me personally, I wouldn't want to get a third person involved in the situation, especially if the relationship should become serious before everything is signed, sealed and delivered. Heal yourself first and then think about dating.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
