My MLCer is in Replay and she is more the low energy type. I like the term Replay, because it acurately decribes what my (ex) wife wants....a Replay. Here are a few things she said or did over the last 6+ months....
Bomb drop was that she wanted a divorce. Her terminology included that we were "growing apart" and she "always had doubts". She said she wanted a "new life". Yet, she had NEVER said either of those things at any time in the previous 17 years. She also said she wanted to "date other people". I was completely caught off guard and did not know what to do. I initiated relationship talks, which usually resulted in anger from her. I did not understand at the time that she did not understand these unusual feelings she was having.
We separated a few weeks later. At that time, she really started spewing anger at me. She blamed me for how she felt. Said I was the cause of the divorce. After we separated, she spent hours and hours on facebook and watching movies.
She filed for divorce, but waffled for a couple of months whether it was what she wanted to do or not. I made it VERY clear that divorce was not what I wanted. We did see a marriage counselor during that time, and it did NO good. In fact, I believe it put more pressure on her. The counselor kept talking about "having to make a decision" regarding divorce. As we know, and as I learned, typically when you pressure an MLCer, they will run.....and divorce is a form of "running away".
My MLCer did not have an affair (at least not physical), did not start drinking, did not do drugs, and did not spend extravagantly. She did file and follow through with divorce (yes, I am still Standing). She has expressed a desire for a new, intimate relationship with someone else. She has expressed desires to run away in several different forms (travel, moving, and job change), but so far the divorce is the biggest thing she has "actively" done.
I guess my point is that the most common trait I see in MLC is the desire to run away or escape. Whether in the same house, separated, or divorced, the MLCer "abandons" the spouse (who they justify as "the cause") and does the running behaviors.
