After looking through the recommended sites that were suggested by the experts I feel that I have a little better grasp on my situation. I feel that my downfalls contributed to our M ending in S. I also feel that my W is going through a MLC. We both went back to school shortly after getting M, now that we have completed our Masters degrees she wants to "enjoy' life and have "fun" and since we were having a 7-8 month rocky patch before I moved out I wasn't part of her wanting to "enjoy" life. This is were the OM comes into play, the MLC she is experiencing took her back to her high school boyfriend which also brought her back to her high school friends and memories. The OM is doing everything right during the "lust" stage of the relationship he is buying her things, placing her 1st 100% of the time and treating her like gold. This is easy to do when the daily in and outs of life don't need to take center stage; they are only seeing each other on the weekends, remember he lives 3 1/2 hours away and they take turns during back and forth.
On another note I have been using the 180 approach, I haven't been pursuing or chasing. I have been letting her contact me; she has called 4 times in the last week. This is hard for me to do since there is OM in the picture and I don't want her moving closer to him instead of me, but I'm doing it. I feel that she has a lot of questions and feelings to answer for herself but I'm hanging in there.
