Pleeeeease do yourself a big favor. Do no read that stuff anymore. I used to be obsessed with researching what goes through the mind of the OW. It didn't bring me any comfort or understanding.
I actually went to a forum for OW/OM today to see what they are thinking and I found it really helpful. But then my situation is a bit different and actually this is the sort of knowledge that can really help me.
I was actually focusing on posts where the OW/OM had been told by other posters that they likely were involved with someone going through a MLC and it was really interesting to see their reactions to that (mostly denial-because they thought it was just all LOOOOVE) and to see that the biggest issue that the OP is dealing with is lies from the affair partner and their shock when learning the truth or the inability to accept that they had been lied to. It made me feel fortunate that at least I can understand the process my husband is going through. Because I sure would not want to be on the other end and have no clue.
