Hey man I feel your pain. My wife dropped the Bomb on me Christmas Day too. All I can say is what others have told me...DO not pursue...work on you...She needs space...she is thinking of you and you may even get some backlash from her because of your changes be prepared...Also know that she is watching EVERYTHING so ask yourself if this will move you closer or farther away from where you want to be. I am in the hard place right now of learning to detach and it is throwing her for a loop. Nothing here is guaranteed but I have seen some results pretty quickly. I understand about the EA as mine is having one too over the internet and they are supposedly in love. Do not engage in conversation about the EA you WILL lose! Get him out of your mind...As a matter of fact do not let the Monkey Mind get you at all...You need to figure out what her needs are that are getting met in this and then start doing it better but very subtle. Read the 5 Love Languages it has helped me before I have even had a chance to implement anything. Above all do not give up hope. Most EAs do not last and end pretty bad. If you back off and stay out of the picture eventually he is going to get comfortable and screw up...read and do 180s that has been a huge help for me.
