I whole heartly agree with Phoenix. I remember your situation and reading the long and elicit affair with the other man and how she loved to travel and spend time with him and then come home.
Your Wife is immature and is always looking for someone or something else to make her happy. Maybe she wants to change but doesn't know how or believe she can. Bottom line how long are you willing to wait for what? Take it on and resolve to change together or live apart. Living in limbo is horrible and can only be tolerated for so long. I don't think she is an awful person but she is very lost and since she is the only one who can fix it, you have a very big decision to make. I wish you the best and will keep up with this.
You can control you and I would not have very high expectations for a consistent turn around. I am sorry to say but I have seen or read about this too often. Just remember it is your life and your decision to go on or to move forward with out her. I commend your efforts thus far regardless of your future decisions.
