My H claims that the fog was so thick that he never, ever considered what the consequences might have been or even that I could be hurt by his LTA.
He never thought about how our children would have coped with a broken family, how his family would have reacted, how having unprotected sex could have given me a STD, how he was putting us in debt by spoiling her and neglecting our finances, how the disconnection between us was a result of having a mistress, or even how he and his business partners could have been held legally responsible for any claims she may have made after their affair was blown out of the water.
Sure the fog can be dense. His lasted 15 years.
I'm still not sure I can believe that HE was this dense however.
