Not sure what you're asking by the dynamics of a MLC affair, but generally it is considered a band aid the MLCer uses to cover the pain and avoid dealing with the issues within. It a running tactic for them.
MLC affair fog I believe is referring to the brain chemicals that occur when one thinks themselves 'in love' with the op.
MLCers often find themselves in a fog with or w/o an op present.
Hope this helps. I'm sure others will be along to add their perspectives.
