I found the last couple pages of this thread really insightful. Thank you for your thoughts.
I have been reading a lot in the past couple weeks and had made the connection between MLC and addiction. In my WS's case is seems like it is infatuation/addiction to the OW, but he is also doing a lot of "buying crap to fill a void" under the guise of self-improvement and becoming his new "better" self.
If the buying stuff is also a direct response to stress, then this gives me yet another strong motivation to keep up my detachment and "As if" attitude. If I break down and create a stressful confrontation, I know know very consciously what the result will be. Either prolonged periods of him leaving the home and making no contact, and/or that he will soothe his ego with another purchase.
It helps enormously to be able to see these patterns of cause and effect so clearly and logically. Thank you!
